There are still some useful syntax checks for performing on ALL files
(for example, prohibit_doubled_word). So I'm not quite sure that
blindly exempting these files from all possible checks makes sense.
Maybe it's worth teaching upstream gnulib syntax-check to make it easier
to auto-exclude non-C files from checks that ARE specific to the C
language, without weakening the global checks that are good on all
files. Maybe even something as simple as adding some sort of language=
tag to feed to $(_sc_search_regexp (if not specified, run on all files,
but if specified as C, the syntax-check is specific to C-like files, so
it limits to .h, .c. .y).
I'm adding the gnulib list to get feedback on the idea; maybe Jim
Meyering has an opinion as one of the original syntax-check authors.
