[PATCH] revset: fix wrong keyword() behaviour for strings with spaces

[Alexander Plavin]

It is a simple resend of this patch, with no changes. As written in the wiki, "Feel free to resend patches after a few days if you haven't gotten a response", and last time I sent it on August 5. Actually, it's not even "a few days", but I just forgot to send it before :)
