On feature I miss from ksh is 'trap "" ERR'.  For example, my .ksh
file has

trap 'echo "(ERR:$?)"' ERR

I tried to simulate this in bash with PROMPT_COMMAND, but it didn't
work.  Here's an emacs M-x shell script: it starts out in ksh, and
then runs bash.

/tmp> (exit 1)
(ERR:1)
/tmp> /usr/local/src/dist-bash/bash
/tmp> PROMPT_COMMAND='if [ $? -ne 0 ] ; then echo "(ERR:$?)" ; fi'
PPROMPT_COMMAND='if [ $? -ne 0 ] ; then echo "(ERR:$?)" ; fi'
/tmp> 

/tmp> (exit 1)
((exit 1)
/tmp> 

bash doesn't print the error status.  Also note that bash doesn't
behave well under emacs, but I assume this is related to previous
reported bugs with determining interactive status.
