pull: do nothing on --dry-run
Pull was never meant to take --dry-run at all. However, it
passes unknown arguments to git-fetch, which does do a
dry-run. Unfortunately, pull then attempts to merge whatever
cruft was in FETCH_HEAD (which the dry-run fetch will not
have written to).
Even though we never advertise --dry-run as something that
should work, it is still worth being defensive because:
1. Other commands (including fetch) take --dry-run, so a
user might try it.
2. Rather than simply producing an error, it actually
changes the repository in totally unexpected ways.
This patch makes "pull --dry-run" equivalent to "fetch
--dry-run".
