convert: pass absolute paths to git (SEC) Fixes CVE-2016-3105 (1/1). Previously, it was possible for the repository path passed to git-ls-remote to be misinterpreted as a URL. Always passing an absolute path to git is a simple way to avoid this.

init repo

  $ hg init foo
  $ cd foo

ill-formed config

  $ hg status
  $ echo '=brokenconfig' >> $HGRCPATH
  $ hg status
  hg: parse error at * (glob)
