As discussed on the git email list [1] with the subject
"Fetching tags overwrites existing tags" there is a bug
where fetching tags can overwrite existing tags.

Ævar Arnfjörð Bjarmasono, has created a patch series [2]
which requires a '--force' flag when fetching if the user
actually wants to overwrite any existing flags.

This patch series allows tags in remotes to be placed in
a sub hierarchy, refs/remote-tags when "git remote add" is
passed the --remote-tags option.

The patch series also modifies tag so "git tag -l" will list
tags in refs/remote-tags properly. It also test for
"git remote add" which uses "git tag -l".
