>Description:
When reply_regexp is set to "^re: *" in ~/.mutt/muttrc, the subject generated 
when replying to emails has one extra space. When reply_regexp is changed 
during a mutt session, and then changed back to the original value set, the 
extra space goes away.
>How-To-Repeat:
Put
    set reply_regexp='^re: *'
in ~/.muttrc. Then load mutt. Reply to a message whos subject begins with 
"Re:". The subject of the new message will be like "Re:  Original subject" 
(note the extra space).

Now do
   :set reply_regexp='asdf'
   :set reply_regexp='^re: *'
and reply to the same message you replied to earlier. The extra space 
dissapears, and the subject of the new message is "Re: Original subject" as it 
should be.
