Finally, after a very busy day of using bash with no problems, this
happened again and 'echo' was off (-echo).

The command triggering the problem was mpv, which I invoked from a
bash prompt to listen to an mp3 podcast file.

I noticed a warning message that mpv was linked against an earlier
version of ffmpeg than the one I have installed now (I'm on ~amd64 so
my rate of package turnover is quite high, naturally).  IIRC the
warning message was displayed in a different color from my normal black
font.  I think this may be true of other instances as well, not sure.

Anyone know of a mechanism that allows an app like mpv to set -echo?

BTW, I typed 'reset' which evidently restored 'echo' (now I can see the
characters I type) but the 'Backspace' key produces '^H' on the
terminal instead of deleting characters.

Next time this happens I'll include the output of stty -a.
