When I use this function, with bash-3.2.39 and whatever the current versions
of rxvt and mc are on Red Hat and Ubuntu, I get an mc error:

Cannot get terminal settings: Invalid argument (22)

(which is indeed EINVAL).  Unsurprising if its stdout is still the command
substitution pipe at that point.

Did you have any luck with the version of the function I sent that runs mc
in the foreground?
