[the `ls' is not expanded]

A simple work around for both ksh and bash is the following:

alias exec="exec "

Then the word following the `exec' will be checked for aliases and
expanded if necessary.  `nohup' is handled the same way.

I don't think that all words of a command should be checked for aliases
and expanded.
