fg jobs info

[Atom Smasher <atom@xxxxxxxxxxx>]

hypothetical example....

% jobs
[1]    suspended  sleep 30
[2]    suspended  sleep 31
[3]    suspended  sleep 32
[4]    suspended  sleep 33
[5]  - suspended  sleep 34
[6]  + suspended  sleep 35

now, if i run 'fg' or 'fg %n', how can i make the command name (sleep xx) 
available to the shell?

why i want this: i've tweaked my ~/.zshrc file to fill in the tabs of 
mrxvt (and the windowlist in screen) with the current command name (and 
some other goodies, i'll post the rc file if there's interest). ie; i can 
quickly find the 'emacs somefile' tab (or screen) because the tab (or 
screen) says "emacs somefile". cool. but if i suspend the command, then 
bring it back with 'fg', the tab (or screen) now says "fg". not cool.

there are some hacks to get around this, but they're not pretty. i'm not 
sure if this can be done elegantly, without requesting a new feature that 
puts the ~real~ foreground command into an environment var, and/or a 4th 
argument to preexec.

unless there's a way to simulate the fg command (ie; a "-n" dry run 
argument) i think the best way to handle this (ideally) would be a 4th 
argument to preexec that contains what fg is bringing to the foreground.

any other thoughts?

thanks...
