WIP: document link resolution behavior and design decisions

This commit is starting as attempt to add useful context for link functions
in the comments / docstrings, and clean up a few things for better
readability.  This is preliminary work for a solution to:

https://github.com/vimwiki/vimwiki/issues/1271

...which is gradually becoming a description of everything that's wrong
with how VimWiki links to files, more or less.

It includes a decision document, which should become a full description
of the problem and steps taken.

This commit _will_ be rewritten.

Bug: #1271

+= VimWiki file link resolution =
+
+A decision document started by Brennen Bearnes on 2023-03-23.
+
+== context ==
+
+https://github.com/vimwiki/vimwiki/issues/950
+
+https://github.com/vimwiki/vimwiki/commit/d7ec12645a0460a7d200279c52915e6e080e9869
+
+Commit d7ec126 applies the wiki extension to files containing a `.`, thus
+allowing page names to contain a literal period.  This is correct behavior,
+insofar as pages like `Franklin D. Roosevelt` should be able to exist and get
+mapped to e.g. `Franklin D. Roosevelt.wiki`.
+
+Unfortunately, this broke behavior that a number of users rely on:
+
+https://github.com/vimwiki/vimwiki/issues/1271
+
+    I have some latex files stored and linked to in my wiki.
+
+    Before d7ec126 I could omit the file: part of a link to have vim open the file
+    directly.
+
+    After d7ec126 vimwiki adds a `md` extension when opening any file which
+    results in a `filename.tex.md` being created alongside the original tex
+    file. Using `file:` is not a solution since this can only be configured to
+    open a second instance of vim.
+
+It makes sense that this is useful.
+
+Sidebar: `file:` _can_ be configured to do just about anything with a custom
+handler, but that doesn't mean it's a very good user experience.
+
+= possible solutions =
+
+== revert to original behavior ==
+
+As a default, I personally think this is a non-starter.  Not being able to use
+`.` in page names is broken.  I also suspect other things break if you treat
+those files as wiki pages.
+
+We could make it configurable, though.
+
+*Pro:*
+
+  - People can go back to their expected behavior by setting one config
+    variable.
+
+*Con:*
+
+  - Adds an extra branch to link handling code.
+  - I haven't thought through the implications of treating it as fully
+    supported behavior.  What else will people expect to work right?
+
+== check if a file exists on disk when following link ==
+
+The idea is that if a link is `[[foo.txt]]` and `foo.txt` already exists, we
+should edit the existing file instead of creating a `foo.txt.md`.
+
+*Pro:*
+
+  - Might be the closest to expectations of people who rely on the old
+    behavior.
+  - Doesn't expand the language itself.
+
+*Con:*
+
+  - Complicates link handling code.
+  - Parsing a page requires knowing about external files.
+  - Might be surprising / confusing.  You can write `foo.txt` and wind up with
+    two different outcomes depending on whether `foo.txt` already exists.
+    - It's very Do What I Mean, which isn't necessarily bad.  But if I write a
+      link to `foo.txt` and wind up at `foo.txt.md`, it's not obvious that's
+      what I meant.
+
+== add a link scheme that means "open in vim" ==
+
+Something like `[[edit:foo.txt]]`.
+
+I vaguely think there's prior art for this in some older browsers?  I could
+swear Lynx had something like it, although I couldn't find anything under:
+
+  - [[https://en.wikipedia.org/wiki/List_of_URI_schemes|wp:List of URI schemes]]
+  - [[https://lynx.invisible-island.net/lynx_help/lynx_url_support.html|list of Lynx URL schemes]].
+
+I may just be thinking of `lynxexec:`.
+
+*Pro:*
+
+  - People want this anyway, and a `VimwikiLinkHandler()` for using `file:` or
+    some custom prefix to handle it is a common tweak to configurations which
+    we already document.
+  - It doesn't need a file existence check.
+
+*Con:*
+
+  - Expands the language.
+  - How is this converted to HTML?
+    - What will Markdown parsers do with it?
+  - Right now there are at least 3 high-level paths for opening a link:
+    - Open in VimWiki
+    - Hand off to custom link handler
+    - Open with `vimwiki#base#system_open_link()`
+    - ...this would introduce a 4th.
+  - Unless there is prior art, this would be something that _looks_ like a
+    URL/URI, but isn't recognized outside the wiki.  That seems fine for
+    custom prefixes, but is it ok to introduce here?
+
+== add a configuration toggle for opening file: links in vim ==
+
+Add a boolean that says "just open `file:` and `local:` links in the editor".
+
+*Pro:*
+
+  - Probably a relatively simple change.
+  - Might meet some users' needs.
+
+*Con:*
+
+  - Loses the utility in linking to binary filetypes which are best opened via
+    the system handler (images, PDFs, etc.).
+  - Users are explicitly already relying on `file:` links to be distinct from
+    `[[file.foo]]` links.
+
+== add configuration for a set of filetypes to open in vim ==
+
+A variation on the toggle for `file:` links would be to allow configuring a
+_list_ of file extensions which should be opened with Vim rather than passed on
+to the system handler.
+
+Something like:
+
+{{{vim
+  let wiki.file_link_edit_ext = ['txt', 'csv']
+}}}
+
+*Pro:*
+
+  - Doesn't expand the language.
+  - Doesn't have any implications for HTML rendering.
+  - A lot of `VimwikiLinkHandler()` boilerplate that is just used for making
+    links open in Vim could go away.
+    - I have this in my own config, so it's an appealing feature.
+
+*Con:*
+
+  - Does require people to rewrite existing link collections, but that's
+    true of other solutions as well.
+
+*Unanswered:*
+
+  - Would there be any sensible default for this besides an empty list?
+    My guess is not.
+
+= open questions =
+
+  - What is the actual current behavior with Markdown?
+    - Does it differ meaningfully from vimwiki syntax?
+    - If so, why?

The opening $ must have a non-space character immediately to its right, while the closing $ must have a non-space character immediately to its left, and must not be followed immediately by a digit. Thus, $20,000 and $30,000 won’t parse as math. If for some reason you need to enclose text in literal $ characters, backslash-escape them and they won’t be treated as math delimiters.

The opening and closing delimiters must belong to separate delimiter runs. If one of the delimiters can both open and close strong emphasis, then the sum of the lengths of the delimiter runs containing the opening and closing delimiters must not be a multiple of 3 unless both lengths are multiples of 3.
