Subject: gitweb: Fix "Use of uninitialized value" warning in git_feed
X-Git-Tag: v1.5.2~5
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=c906b18122af72a8219c76281473490f812e5a40;p=git.git

gitweb: Fix "Use of uninitialized value" warning in git_feed

Initial (root) commit has no parents, and $co{'parent'} is
undefined. Use '--root' for initial commit.

This fixes "Use of uninitialized value in open at gitweb/gitweb.perl
line 4925." warning.
