Message:: allow remotes without urls in git config Also, add tests. This change lets got and related tools work when the git config file has "remote" sections without urls, like this one in one of my git-annex git repositories: [remote "h0-rsync"] annex-rsyncurl = (some url) annex-uuid = (some uuid) skipFetchAll = true Running tog and many got commands there would previously result in: $ tog got-read-gitconfig: gitconfig syntax error tog: gitconfig syntax error The change to got-read-gitconfig.c is by stsp@, with ok from op@ (and now me). Tests ok stsp@.
