Subject: git-svn: give show-ignore HEAD smarts, like dcommit and log
X-Git-Tag: v1.5.1-rc1~146
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=1a97a506043691741f25e8967e76123c1114d1fb;p=git.git

git-svn: give show-ignore HEAD smarts, like dcommit and log

This allows the user to run git-svn show-ignore on there
current HEAD without needing to remember which branch/ref they
branched from with -i.  Also, find_by_url should correctly
handle cases where the URL passed to it is not valid.
