[PATCHv2 0/3] Be more careful when prunning

["Carlos Martín Nieto" <cmn@elego.de>]

Hello,

The first patch is not that big a deal, but it's better if we're
freeing the refspecs, we might as well free all of them.

The second patch teaches get_stale_heads to use the user-provided
refspecs instead of the ones in the config. For example, running

    git fetch --prune origin refs/heads/master:refs/heads/master

doesn't remove the other branches anymore. For a more interesting (and
believable) example, let's take

    git fetch --prune origin refs/heads/b/*:refs/heads/b/*

because you want to prune the refs inside the b/ namespace
only. Currently git will delete all the refs that aren't under that
namespace. With the second patch applied, git won't remove any refs
outside the b/ namespace.

What is probably the most usual case is covered by the third patch,
which pretends that a "refs/tags/*:refs/tags/*" refspec was given on
the command-line.

Version 1 assumed that a refspec would have its dst filled
automatically. This is not the case and was fixed in the second patch.

Cheers,
   cmn

      fetch: free all the additional refspecs
      fetch: honor the user-provided refspecs when pruning refs
      fetch: treat --tags like refs/tags/*:refs/tags/* when pruning
