Hi,

sometimes I forget that I just tagged a release and tag it again; which
is not nice. "darcs tag x" should give a warning if "x" is already in
the repository and ask if I really want to tag it.

Bonus points if it tells me whether the existing tag is the top-most
patch, i.e. if I am about to tag the exact same state as before, or
whether I was about to tag something different.

Thanks,
Joachim

I am marking this as urgent. This is a long-standing problem with darcs
and a warning would at least help reduce the probability of fatal mistakes.

Querying a tag from a repo was is a cheap operation, since it's only a
matter of scanning inventories. And yes, this would be a UI improvement.

The following patch sent by Ale Gadea <alex.aegf@gmail.com> updated issue Issue2244 with

Make darcs tag t, with t already an existing tag, cause a warning message.
