Feature request - a flag to modify subject only

[Michail Vidiassov]

Dear Developers,

what about Subj?

It seems to take no more than a couple of lines of code.

The existing -m flag turns on/off Subject and body modifications
simultaneously.

But
1) Changing Subject is useful for non-technical users, who
   are unable process mail based on X-Spam headers.
2) Leaving body unmodified is importnat, since some
   users strongly oppose any changes in the mail content
   and tend to blame spam filters for any unreadable mail they get.


BTW. Why the following is just a comment (in the code processing -m option)?
// smfilter.xxfi_flags &= ~SMFIF_CHGBODY;
If it does not change how the program works -
it still make the reader of the code feel safer.
(Like "DO NOT PANIC" written in large friendly letters ;).

                   Sincerely, Michail
