My request is simple. Using termcap/ncurses info (which you need anyway
for the readline stuff), it would be nice to have the option of running
commands in a pseudo-tty and then bracketing the output from STDERR with
<highlight on>...<highlight off>.
This doesn't strike me as remotely within the domain of responsibilities
that should belong to bash, mainly because:
1. it has nothing to do with anything that shells normally do.
2. putting it in bash specifically, would rob other, non-bash related
commands, the possibility of having such a feature.
It wouldn't be difficult to write as a separate program, which is really
how this should be handled. You could redirect a pipeline's STDOUT and
STDERR to individual named pipes (FIFOs), and have a separate program
read from both pipes, inserting highlights around any data it copies
from the STDERR pipe.
