[PATCH 2/5] gitweb: No difftree output for trivial merge

["Jakub Narebski" <jnareb@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 504 bytes --]

In 'commitdiff' view, for the merge commit, there is an extra header
for the difftree table, with links to commitdiffs to individual
parents.  Do not show such header when there is nothing to show, for
trivial merges.

This means that for trivial merge you have to go to 'commit' view
to get links to diffs to each parent.

It looked a bit stupid, lone "_1_ _2_" links.
