[libvirt] [PATCH 2/2] maint: reject raw close, popen in 'make syntax-check'

> (sc_prohibit_fork_wrappers): New rule, for fork, system, and popen.
> * .x-sc_prohibit_close: More exemptions.
> * .x-sc_prohibit_fork_wrappers: New file.
> * Makefile.am (syntax_check_exceptions): Ship new file.
> * src/datatypes.c (virReleaseConnect): Tweak comment to avoid
> false positive.
> * src/util/files.h (VIR_CLOSE): Likewise.

Shouldn't the dot be escaped here like in the other lines you added?

And here too, although this one is pre-existing.

ACK, with that nit fixed.
