I was basing my implementation based on the Apache documentation,
and you're correct that it doesn't say anything about userids
being single or double quoted strings.  But since quoted strings
are allowed just about anywhere in an Apache config file, perhaps
they didn't feel that they needed to call it out specially.

At any rate, this makes me feel much better about making
AuthUser handle spaces in usernames and group names (which I
really want for LDAP/AD authentication), so I'll do that as 
part of the 2.2 beta.

Thanks for checking into this for me, I really appreciate it.
