Re: [libvirt] [PATCH 2/2] maint: tighten curly brace syntax checking

Now that hanging brace offenders have been fixed, we can automate the check, and document our style. Done as a separate commit from code changes, to make it easier to just backport code changes, if that is ever needed. * cfg.mk (sc_curly_braces_style): Catch hanging braces. * docs/hacking.html.in: Document it. * HACKING: Regenerate.
