fortunately n-curses devolves tremendously when you don't try to
support every terminal type under the sun efficiently...

Thinking about it, an old school more without ncurses could have the
last few bits of less tacked on top: searching, backwards movement, any
other bits of interest?
If we yield on fine cursor control and efficiency we could just print
the screen...
It is not like we are trying to be efficient on a ADM-3 or a teletype
over a slow serial connection...

You can always tell me what those adaptations are, and I can see if I
can make them.

Your new sed implementation would have some infrastructure that might
be shared by boxes. Lots of the editing stuff in a few of the editors
is essentially identical to sed, using the same commands. Any editor
will have similar infrastructure for dealing with files, lines, actual
editing, and such.
So maybe during the Christmas break (new $DAYJOB means I get paid
holidays for a change), I'll go over toybox sed and see what I can
reuse for boxes.

A big old stinking pile of genius that no one wants
coz there are too many silver coated monkeys in the world.
Personally I have a strong bias toward simplicity, a major reason I
like aboriginal and toybox and would like to see qcc ( also being a 60X
faster is nice too 14s vs 14m from tar file to executable compiler :)
I am would suggest something like GNU_QUIRKS and POSIX_QUIRKS config
symbols to add in the odd features like gnu sed directly disagreeing
with POSIX or POSIX's umm interesting xargs without -0 quoting
conventions and any other "why did they do it that way" I know POSIX is
nice to adhere too, but some of the stuff is just odd, and I at least
could live without complex code that does not do anything that I want,
and just complain for example on xargs without -0 and weird filenames.
Hopefully nobody depends on e.g. the sed N;N working like gnu choses, I
am not fond of bug to bug compatibility.
Just like I would prefer to modify glob to output "ls ./-c" for "ls *"
instead of modifying the kernel to not accept "-c" as
a legal file name or try to escape it in the kernel like wheeler wrote
about.
This will be my first email sent from balsa, hotmail improved things
again. So now that I have downloaded my 3G of email in 71314 messages
through IMAP4/SSL, hotmail's server was both slow and goes bonkers
after only 60min of downloading and errors out, so I have been
downloading in a loop.
