Subject: [PATCH] Add option to not conceal one-character markers

Adds new configuration variable, "conceal_onechar_markers", defaulting
to on (preserving default behaviour)

Adds if-statement around relevant parts of code (as suggested in the
issue), which uses the new configuration variable.

Fix #315 - Don't conceal one-character markers
