diff from stdin about toybox HOT 2 OPEN

Sorry for the delay, I was doinig a complete rewrite of diff last year which got parked, and I'm going "I should probably try to finish that and promote it this weekend".

Diff is in pending, so I treat it with slightly less urgency, but if somebody's waiting for it I need to bump it up, but I'm trying to finish rewriting/promoting fold.c before opening the next can of worms, and went down a utf8 rabbit hole on that which resulted in redoing demo_utf8towc.c...

It's not quite https://xkcd.com/349/ but there's some can-of-worms nesting going on. Not unusal around here, to be honest...

No issue with the delay. I was just reporting the issue which is probably going to be rare in practice on desktops and is more likely to happen in locked down embedded systems. I patched it to check if current location is writable else fall back on /dev/shmem which is always available on QNX. That may not be the case on other operating systems.

I fully understand that refactoring can be thought as a simple exercise until you get into the weeds. Reminds me of renovating a house and you haven't opened the walls yet to see what lurks.

You own the schedule on what is promoted, I'm not asking/expecting any favorable treatment from this reporting.

Thanks!
