Subject: [PATCH] URI-escape the '@' character.

Ensure that the '@' character is escaped in strings.  This isn't necessary
now, but in the future this might be useful so that indirect references are
never ambiguous.  (If a "@" appears, it's an indirect reference; if a
literal "@" is needed, it is escaped.)
