Subject: Fix in vc-ignore-dir-regexp
Date: Fri, 27 Apr 2007 20:57:50 -0700 [thread overview]
Message-ID: <17970.50750.556614.101415@gargle.gargle.HOWL> (raw)
In-Reply-To: <E1HhXEH-0004y5-F5@fencepost.gnu.org>
I had reported a related bug many months ago about VC being too
aggressive with defaulting to the number of versioning systems
that it wants to support.
I suggest that we take out all except svn cvs and rcs from that
list.
In particular vc systems that need to ascend the directory tree
looking for vc directories should not appear in the default list.
