Yeah I get it np. Your call. The risks are low I'd say.

I later got that too. The gdb manual states that gdb.ini is the official
name of gdb on DOS systems. I think it should be fine as the chance for
false-positives in low on this one.

I think so yes. In most instances the .in extension should also match
the preceding match it I think.
