you're suggesting a mail client that can take an existing file that
contains an RFC822-formatted message, and will let the user sign and
send it without this kind of stuff:

i'd like to know which mail clients you use that really make that
workflow easy :)

PGP/MIME will preserve the whitespace.  Inline PGP signatures are a
whole other kettle of (messed up) fish, and should not be attempted.
