Subject: [PATCH] Added support for + symbol response in RE_PRECEDING regex.

In case of IMAP IDLE some servers give time breakup in their response. Running RE_PRECEDING regex over it was falsely matching + symbol but at a wrong place (some where in the mid). It should be only matching at the first place.
