- fixed the %U macro so that the old (and documented) semantics work
again. This got broken with one of the substitute.c updates a couple
of months ago.
- also fixed %u to return the username from the current_user structure
when called via a method that does not have direct access to the
username. I cache the uidtoname() result to prevent thrashing nss.
(This used to be commit 2520a0eff9c5decbec79aababe9910db3535890a)
