Subject: [TOPGIT] limit rev-list in branch_contains to a single rev
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=topgit.git;a=commitdiff_plain;h=991921b9e0009b6127e0c3d996c682bee555b99b

[TOPGIT] limit rev-list in branch_contains to a single rev

This eases reading of debug output using sh -x and probably helps
performance, too.
