Bug-Description:
|
||
|
|
|
||
|
|
There are some cases where the shell reaped a background (asynchronous) job
|
||
|
|
and would incorrectly try to set the terminal's process group back to the
|
||
|
|
shell's. In these cases it never set the terminal process group to that
|
||
|
|
jobs's process group initially, so resetting it is incorrect.

||
|
|

||
|
|
