It isn't overridden so much as ignored, the lexer is for a specific
language, and for any language the comments are defined so the lexer
doesn't need to look at any settings.  The lexer knows nothing about your
attempt to (ab)use it for a similar language.

Sadly the problem is similar, but this time with parsers from the Ctags
project.  Those parsers find the symbols in open files that are shown in
the symbols tab.  Again there isn't an Awk parser in Geany.
