[PATCH] gitweb: Remove "uninitialized value" Perl warning

From: Øyvind A. Holm <sunny@sunbase.org>
Date: Jan 12, 2016, 03:31 UTC
Message-ID: <1452569516-25657-1-git-send-email-sunny@sunbase.org>

git_object(): Check if $type is defined before chomping it. This removes a Perl warning in the server error log:

  gitweb.cgi: Use of uninitialized value $type in scalar chomp at
  [...]/gitweb.cgi line 7579., referer: [...]

when trying to access a non-existing commit, for example:

  http://HOST/?p=PROJECT.git;a=commit;h=NON_EXISTING_COMMIT
