patch to mask top bit when displaying articles

[G. Paul Ziemba]

I finally got annoyed enough at nn sending my xterm into goofball mode
due to non-ascii characters in posts that I made this quick and dirty
patch to mask off the high bit of characters sent to the terminal.

I'm open to suggestions for a better way to do it.

This patch is based on nn 6.7.3.

put "set term-7bit true" in .nn/init to enable.

NN currently has a setting data-bits which should do what you want. It
also has charset which you might also want to check out.

Me, I got tired of NN not knowing how to handle quoted-printable in
messages, so I have been looking at doing better UTF-8 support. My terminals
all support 8bit characters, so I usually set data-bits to 8 and charset
to utf-8, which NN does not recognize, for now.
