I considered that approach, but felt it would always be flawed by space
also being a delimiter in the active file. This patch puts quotes around
the group names when *writing* the active file of agent & cache (and
escapes any \ or " in them). I've been using it and I think it's clean.

But I'm not a position to actually test it with nntp, or IMAP folder names with 
\ or ".
