Great to have a curses full-screen browser! Something we has always throught ought
to be done, but hadn't had the time. Send me the patches, and I'll insert them
into our current code and into the next release.

Sounds like a PC-sepcific bug there... but you never know. We have found something
weird with realloc() under aix but that looks like an aix bug.

I think this may be Edit on the NeXT which is happy to leave an uncompleted line on
the end of a file. I'll have to look at it.

Assuming your patches are useful -- which they certainly have been up till now,
we'll incorporate them into the release.

yes please!
