Subject: * The first git commit legitimately has no parents. Avoid recentchanges
X-Git-Tag: 2.12~4
X-Git-Url: http://git.vanrenterghem.biz/git.ikiwiki.info.git/commitdiff_plain/8ffa59e6104be71b043b835920cb34d837b91fbf

  spewing uninitialised value warnings and debug messages about it.
  Dummying up a parent of 0000000 allows gitweb to work too.
