[PATCH] git-fetch.sh: fix fetching of tags that point directly to commits

[Petr 'Patch Proxy' Baudis <pasky@ucw.cz>]

git-fetch used to fetch only tags that pointed to tag objects,
because it required a ^{} suffix from git-ls-remote's output.

Curiously enough, Junio himself posted a patch. Perhaps given his state
as of then he forgot to fix Git as well. ;-)

I did not write this patch. One fellow IRCer did, but for personal
reasons he does not wish to disclose his realname. I think the patch is
trivial enough that copyright problems should not be a issue.
