It leaves the rest of the lines blank, but, since most lines would be over
40 characters anyway, (the standard braille line length on paper), you
wouldn't have to reformat the buffer by starting a new print line on the
same braille line of the previous print line just because there was room
left on the new braille line. That would get too messy and I think, it
would be too hard to program. The only reformatting you would want to do,
and this is not a requirement really, might be to use two spaces instead
of five spaces for a new paragraph. And you could delete blank lines from
the display buffer when translating. Maybe brltty could have two buffers,
a computer braille buffer and a grade two buffer. Also, I think you would
want this feature to be a plug-in compatible option like the synthesizer
drivers or make it library code. Maybe you could borrow code from nfbtrans
package or turbo-braille code that was ported to linux.

just some thoughts. I am not a C++ programmer. I was a COBOL programmer
until three years ago, though.
