Some people in #linux-rt claimed that you cannot define "--mirror" with
"mirror".

I'd say "mirror" is a commonly known term for an exact copy. Moreover,
the text below doesn't explain what a mirror is either, only how
"update" behaves in it.

hmm.  The --mirror option doesn't have any effect (apart from the
changes in the config file) until you update.  So I think it's natural
to talk about git update.  No?

the way it's written it refers to the preceding command.

So what do you think about:

Again, "this" refers to the preceding sentence. But the update behavior
does not imply "--bare". Specifying "--mirror" for "clone" implies "--bare".

OK.

That's not true. It just doesn't touch any local branches; it updates
the remote branches, of course.

Hmm, for me there are no remote branches when using --bare:

	ukleinek@cassiopeia:~/tmp$ git clone --bare ~/gsrc/topgit
	Cloning into bare repository topgit.git...
	done.
	ukleinek@cassiopeia:~/tmp$ cd topgit.git/
	ukleinek@cassiopeia:~/tmp/topgit.git$ git remote update
	Fetching origin
	From /home/ukleinek/gsrc/topgit
	 * branch            HEAD       -> FETCH_HEAD

This is also documented for --bare:

	When this option is used, neither remote-tracking branches nor
	the related configuration variables are created.

Best regards
Uwe
