[libvirt] [PATCH] network: fix indentation of networkDnsmasqConfContents

Laine Stump laine at laine.org
Thu Dec 13 16:46:50 UTC 2012


Somehow I managed to push the changes to this file with improper
indentation. This patch just re-indents, reformats the comment lines,
and re-groups a couple of multi-line strings so that they fit within
80 columns. The resulting binary should be identical.

I'm *not* pushing this as trivial, because the strings were re-grouped
and a 2nd set of eyes verifying I didn't botch anything would probably
be a good idea. (I did successfully run make syntax-check and make check).
