git fetch --tags doesn't quite do what I expect

[Tony Luck <tony.luck@gmail.com>]

I've been doing some updating on my git scripts to make use of the features
that you have been working hard to put in (thank you).  My script to update
my local "linus" branch from Linus' master branch at kernel.org had a simple
"git fetch linus" (with the appropriate[1] URL and Pull lines in
.git/refs/remotes/linus)
followed by an unholy piece of script that parsed the output from
"git-ls-remote --tags linus" to see if I had all the latest tags, and
get them if
I didn't.

Looking at the manual, I thought that I could just change the "git
fetch linus" to
be "git fetch --tags linus" and drop the script.  But it appears that
with the "--tags"
argument the "fetch" will not fetch anything beyond the tagged commits (i.e.
at the moment v2.6.15-rc1) ... so I need both:
      git fetch --tags linus
and
      git fetch linus

one to get any new tags, and the other to fetch all the way up to "master".

Is this intended behaivour?  If so, the "--tags" entry on the git-fetch(1) man
page needs a little extra text to say that --tags limits the fetch to only
commits reachable from the tags.
