Subject: setlocalversion wasn't producing git labels for bisect

Trying to do a bisect with git version 1.5.6.3 didn't work with the setlocalversion script

Running
  git name-rev --tags HEAD
gives the output
  HEAD tags/v2.6.27-rc4~44^2

This isn't matched by setlocalversion regexp so it makes it harder to make deb-pkg/install/grub/reboot/remove

Of course if this patch is accepted it is going to make life complicated when bisecting around it.
Maybe git should behave as the man page suggests and have the ^X before the ~nnn? (maybe it has been fixed already)
  http://www.kernel.org/pub/software/scm/git/docs/v1.5.6.5/git-name-rev.html
shows an example:
  33db5f4d9027a10e477ccf054b2c1ab94f74c85a tags/v0.99^0~940
