[PATCH] checkout: abbreviate hash in suggest_reattach

[Kevin Bracey]

After printing the list of left-behind commits (with abbreviated
hashes), use an abbreviated hash in the suggested 'git branch' command;
there's no point in outputting a full 40-character hex string in some
friendly advice.

I think this makes sense. We generally use the full sha1 when the output
is meant to live for a long time, but that is not the case here.

I suspect I would have been annoyed by it, too, if I did not have
advice.detachedHEAD turned off. :)

Code looks obviously correct to me.
