Ksh use (was Re: Should ``csh'' be part of ...)

[Ron Natalie]

I understand the reason for having to type fg rather than just %1
in the KSH.  When I put job control in the Bourne shell (prior to
the public release of KSH), the %n expansion is implemented in
the same way as the substitution of shell variables.  Builtin commands
are a little tricky so you have to actually type the name of the builtin
command (fg, bg) inorder to make it work.
