Re: [libvirt] [PATCH] build: exclude more files from all the syntax checks

the checks already cause false positives for non-C sources (and thus
there are exclusion regexps in place).
Instead, just exclude more non-C files from all the checks:
- pot files: they are templates for po files (already excluded), and
they are automatically generated from sources
- pl files: Perl sources, which have own APIs, style, etc; they are
helper scripts, not "real" sources
- spec/spec.in files: RPM packaging files
- js/woff/html.in files: files for web pages
- diff/patch files: patches
- stp files: SystemTap scripts
- syms files: linker symbols files
- conf files: generic configuration files
- data/cpuinfo files: procinfo/cpuinfo files
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.
Python files (.py) are left allowed, since there is at least one syntax
check specifically for them.
