[PATCH 0/5] Builtin "git remote"

This patch series puts a few building blocks in place (the first three patches), builds in "git remote", and fixes the current behaviour of "git remote prune" when the remote was initialized with --mirror.

It incorporates Hannes Sixt's comments about checking remote_nr.

Oh, and in contrast to the earlier series, I removed the DWIM "git add remote" patch.

It also demonstrates that format-patch --cover-letter should default to -M for the diffstat (search for "git-remote.perl"...).

Johannes Schindelin (5):
      path-list: add functions to work with unsorted lists
      parseopt: add flag to stop on first non option
      Test "git remote show" and "git remote prune"
      Make git-remote a builtin
      builtin-remote: prune remotes correctly that were added with --mirror
