[PATCH RESEND] subtree: force merge commit

[Johannes Altmanninger <aclopte@gmail.com>]

From: Thomas Koutcher <thomas.koutcher@online.fr>

When `merge.ff` is set to `only` in .gitconfig, `git subtree pull` will
fail with error `fatal: Not possible to fast-forward, aborting.`, but
the command does want to make merges in these places. Add `--no-ff`
argument to `git merge` to enforce this behaviour.

I think this was meant to be queued but forgotten.

Changes since v2: removed/added reviewed-by trailer

BTW is there a good way to tell "git send-email --in-reply-to"
to prefill "To:" and "Cc:" based on the message I'm replying to?
