As far as I know, it's is prefectly valid to add any random number of
arbitrary non-standard args.  So "format=[a-z]+" is too restrictive.
We'd probably want something more like:

   (concat "^content-type:[ ]*text/plain;"
           "\\(?:[ \t\n]*[-a-z]+=\\(?:[^\";]+\\|\"[^\"]+\"\\);\\)*"
           "[ \t\n]*charset=\"?\\([^ \t\n\";]+\\)\"?")

although I can't remember the exact BNF rules for this MIME header, so it
can probably do with a bit more work.
