Tinmarino 72d02207b0 Syntax: Fasten highlighting, from 200ms to 20ms for first screen update
Problem:

The loading of a .md file was slow due to multiple nested lookback.
It is advised in vim help to prefer \zs, see :h /\@<
Anyway, it is useless to nest them.

Solution:

Remove the function s:expand_delimiter in vars.vim.
It was doing a duplicate job with vimwiki#u#hi_expand_regex
And ... well avoid lookback as much as possible
