some wrong spelllling. <RET>

M-x ispell-message

you should now be prompted to spell check the word spelllling.  Since
text in the marked parts of messages is usually quoted -- be it text,
code or otherwise -- I propose that we skip spell checking on these
parts of messages.  It can be a real hassle when quoting a large body
of code or text.

Attached is a patch to implement this.  Any comments welcome.

Thanks,
Matt
