I would.

Very.  This would mean an extra keystroke for every exited bash shell...
Yuck.

However, most bash invocations should exit with a 0 exit code.  So, why
not simply do something like the test below?

if not errorlevel 1 goto nopause
pause
:nopause

Also, "command not found" sets error code to 127, so the "1" above can be
changed to "127".
