Most projects that use gnulib do *not* version control the sources,
so for them it's required to ignore everything.  So gnulib-tool
adds those *.c names to .cvsignore files.

Since libvirt is at least the second project that is adamant about
version-controlling gnulib-tool-pulled sources, I plan to add an
option to gnulib-tool to make it's .cvsignore-writing behavior
do what libvirt wants.
