Subject: [PATCH 8/8] gitweb: Remove --parents from call to git-rev-list in parse_rev_list
Date: Wed,  6 Sep 2006 22:56:22 +0200	[thread overview]
Message-ID: <11575761821830-git-send-email-jnareb@gmail.com> (raw)
In-Reply-To: <11575480921132-git-send-email-jnareb@gmail.com>

This option is removed by default, because with --full-history option
(which is by default used in git_history) --parents means full history
with parenthood, which means that we get all the connecting merges
too.  And since we asked for the _full_ history, that means EVERY
SINGLE MERGE.  Even those that do not change given file (or
directory).
