[PATCH 0/3] Iron output of describe --contains --all

Hi,

I actually sent these patches to the list last month, but nobody seemed to be interested. This is an unedited resend.

I looked into adding tests, but decided that it was a lost cause: the output is too loosely defined for any scripts to rely on it strongly. [1/3] already shows a race between branches and tags. For another example, consider two tags are pointing to same commit (D and R in t6120-describe.sh). Run the following on the two tags and see what happens for yourself:

  $ git describe --contains
  $ git describe --all
  $ git describe --tags

Now think about various combinations of these options. I'm not saying that it's a Bad Thing (TM), but that nobody has bothered tightening the output.

My main motivation for doing this series is my prompt: I don't want to see

  artagnon|(tags/v1.8.3^0)~/src/git$

when

  artagnon|(v1.8.3)~/src/git$

is so much more pleasant and consistent. Obviously, hacking around this problem in the prompt script is the Wrong thing to do.

Thanks.
