Subject: hg2git.sh: Try to get last hg repo url from state file
X-Git-Url: http://crossforests.com/gitweb?a=commitdiff_plain;h=61bb1cb70794df21b626159ff164839d7915907e;p=python%2Ffast-export.git

hg2git.sh: Try to get last hg repo url from state file

As one usually mirrors a git repo based on the same hg repo, it's
annoying having to specify the hg repo url all the time. Since we
intentionally stored the url in the state file already, use in the
shell wrapper and default to it.
