Job control is off in the subshell

[DmitryKX]

Vanilla Lubuntu 13.04. Steps to reproduce:

1) run LXTerminal
2) in the opened terminal run "xterm -e su nobody -c su -", enter password

Result: in the opened xterm you will see "Job control is off". It is possible to terminate this buggy xterm with just Ctrl+C.

This worked fine in 12.10.

This is probably a duplicate of #1199547

Are you sure? This one came before #1199547.

Status changed to 'Confirmed' because the bug affects multiple users.

For the special case mentioned (no controlling terminal), this is not specific to xterm,
and is unlikely to be a bug in the terminal emulator.

I just verified that I can see identical results with xterm, urxvt, pterm, konsole and lxterminal.
(perhaps vte-based stuff differs, but it's not worth considering due to lack of command-line compatibility)
