Mathieu Duponchelle cf793d6678 -bad/docs: be more selective about header files to exclude
A few header files in -bad contain comments that start with the
/** gtk-doc pattern, but should not actually be parsed (and warned
about as such).

Previously, we were using far-reaching wildcard patterns to avoid
parsing those, but this had the unintended side effect of also
excluding legitimate files, and creating confusion when comments
were not parsed from those.

Switch to excluding specific files instead.
