hudson's git tags break the git describe output

[sam-github]

When I clone and checkout origin/master:
% git status

On branch master

nothing to commit (working directory clean)
~/s/libnet/libnet.git % git describe
libnet-1.1.4-108-g987fc90

When this happens in hudson:

build@build:/storage/sw/hudson/jobs/libnet/workspace$ git checkout origin/master
HEAD is now at 987fc90... Memory bounds checking using electric fence.
build@build:/storage/sw/hudson/jobs/libnet/workspace$ git status

Not currently on any branch.

nothing to commit (working directory clean)
build@build:/storage/sw/hudson/jobs/libnet/workspace$ git describe
hudson-libnet-5

I can see why some might like this auto-tagging, but it should be optional.

sorry the formatting is broken, there doesn't seem to be a way to disable markdown.

Wish this would be fixed! Using underscore might solve it, ie "hudson_libnet_5"
