After

a transfer encoding, even it the content contains only 7\-bit data. This
is to increase the likelihood that the content is not changed while in

-The switch

-will cause
-.B mhbuild
-to slightly change
-the way in which it performs the \*(lqquoted-printable\*(rq transfer
-encoding. Along with encoding 8\-bit characters, it will now also encode
-certain common punctuation characters as well. This slightly reduces the
-readability of the message, but allows the message to pass more reliably
-through mail gateways which involve the EBCDIC character encoding.
