Before this patch each call to tg remote added three config entries
no matter if they already existed.  After some time my .git/config was
crowded.

What's the "next commit"?

oh, sorry.  I intended to post my patch that implements `tg export
--linearize`, but then found a bug and so didn't send it.

You can find it in my pu branch at

	git://git.pengutronix.de/git/ukl/topgit.git pu

.  It's not yet ready for general use, but I look forward to any
constructive feedback.

Best regards and thanks for the reminder,
Uwe

It seems I sent an old version of this patch.  Actually in the last
argument '+' and '*' have to be quoted to work.

I fixed this in my repo.  Should I resend the fixed patch?

Best regards
Uwe

It'll be a while until I can look into this. Until I do, I will only
pull in f4fa614, and we'll pull ae3fe45 when your linearizing patch
is ready.
