The prefix-only variation for builtin and well-known acocunts is what's
originally used by SFU.  I cloned that behaviour as it seemed to have
advantages handling getpwname/getgrnam calls.

The Windows ".\" prefixing is not at all utilized inside Cygwin.  It has
nothing to do with how the prefixing is evaluated.

That's what you get with db_prefix "auto" or "primary".

Sigh.  YA setting.  I was trying to *simplify* the stuff and reduce
variability since that stuff only complicates the code for... what
gain?
