CVS commit: src/bin/sh

["Robert Elz" <kre%netbsd.org@localhost>]

Module Name:    src
Committed By:   kre

Modified Files:
        src/bin/sh: jobs.c sh.1

Log Message:
Add options to the builtin jobid command to allow discovering the
process group (-g), the process leader pid (-p) ($! if the job was &'d)
and the job identifier (-j) (the %n that refers to the job) in addition to
(default) the list of all pids in the job (which it has always done).
No change to the (single) "job" arg, which is a specifier of the job:
the process leader pid, or one of the % forms, and defaults to %% (aka %+).
(This is all now documented in sh(1))

Also document the jobs command properly (no change to the command, just
document what it actually is.)

And while here, a whole new section in sh(1) "Job Control".  It probably
needs better wording, but this is (perhaps) better than the nothing that
was there before.
