"Use it with care" is a wrong wording to say "this is purely internal
and you are supposed to know what you are doing if you use this".

Johannes noticed the recent addition of this new flag
inadvertently took over existing --update-head-ok (-u).  Require
longer abbreviation to this new option which would be needed in
a rare setup.

Without this, there is no way to specify a remote executable when
invoking git-pull/git-fetch as there is for git-clone.

[jc: I have a mild suspicion that this is a broken environment (aka
 sysadmin disservice).  It may be legal to configure your sshd to
 spawn named program without involving shell at all, and if your
 sysadmin does so and you have your git programs under your home
 directory, you would need something like this, but then I suspect
 you would need such workaround everywhere, not just git. But we
 have these options we can use to work around the issue, so there
 is no strong reason not to reject this patch, either. ]

I added things to ls-remote so that Cogito can auto-follow tags
easily and correctly a while ago, but git-fetch did not use the
facility.  Recently added git-describe command relies on
repository keeping up-to-date set of tags, which made it much
more attractive to automatically follow tags, so we do that as
well.

The option description header was there without body text, confusingly
getting rendered as if the description for --tags applied to the option.

Noticed by Carl Baldwin.

When fetching/pulling from a remote repository the "--tags" option
can be used to pull tags too.  Document that it will limit the pull
to only commits reachable from the tags.
