[tex-live] howto partial svn update?

[Karl Berry]

    svn propset svn:ignore foobar PATH ...

As long as you don't commit the property changes (which seems like it
would be very easy to do by accident).  Then the dirs would start
getting ignored for everyone else, too.  As far as I know.

I don't see any kind of exclude options in the --help messages, although
I did not try to check the full documentation or svn mail archives.
