src/bin/sh: jobs.c jobs.h sh.1
Log Message:
Add '-n' and '-p var' args to the wait command (-n: wait for any,
-p var: set var to identifier, from arg list, or PID if no job args)
of the job for which status is returned (becomes $? after wait.)
Note: var is unset if the status returned from wait came from wait
itself rather than from some job exiting (so it is now possible to
tell whether 127 means "no such job" or "job did exit(127)", and
whether $? > 128 means "wait was interrupted" or "job was killed
by a signal or did exit(>128)". ($? is too limited to to allow
indicating whether the job died with a signal, or exited with a
status such that it looks like it did...)
