[PATCH 0/3] git remote update: Check args and fallback to remotes

This series is on top of next.

git remote update <non-existing> would previously silently do nothing.
With this patch series, it will (with 1/3) error out when non-existing groups
are given, and with 2/3 & 3/3 it will use a remote if a group cannot be found.

This enables "git remote update origin" for example. All previous uses
of "git remote update <x>" that did something useful should still work
exactly as before.

There seems to be no current way to check for the existence of a configured
remote, so 2/3 adds a remote_is_configured() function which checks for a
configured remote.

Finn Arne Gangstad (3):
  git remote update: Report error for non-existing groups
  remote: New function remote_is_configured()
  git remote update: Fallback to remote if group does not exist
