Log Message:
-----------
Cleanup NONE/AUTO filetype definitions
At the moment the Geany code uses arbitrary combination of the following
synonyms
TM_PARSER_NONE / LANG_IGNORE / -2
TM_PARSER_AUTO / LANG_AUTO / -1
Especially using just the numbers makes things very confusing.
In the Geany code this patch replaces all occurrences of -2 and LANG_IGNORE
with TM_PARSER_NONE. It also removes LANG_IGNORE from the header which
isn't needed any more.
In addition, TM_PARSER_AUTO/LANG_AUTO shouldn't be used at all. We want
filetype detection based on Geany's definitions and not based on the
hard-coded ctags definitions. Remove it completely.
Finally, as it's clearer now what the constants mean, the patch fixes the
implementation of langs_compatible() (tag or file can never be of type
AUTO but we should rather check for NONE filetypes which we should
consider incompatible between each other).
