What do you use to quote text? Have code to show me?
Also, what do you use in your MUA to catch quoted strings? Have a regex or Emacs LISP?
As to recognizing quoted material, I use this:
which is tweaked a bit from whatever the stock Mutt config was.set quote_regexp = "^ *[:>]+ "
Mutt takes care of most of it. And for those nastily formatted emails that have been through other email clients there's always Damian's Text::Autoformat which is invoked from vi with this entry in my
map f !Gperl -MText::Autoformat -eautoformat
(that's taken straight from the Text::Autoformat docs - I didn't think of it myself)
