In the man page it states that any job control command can address a job via
PID as well as the % constructs. In the source, only 'wait' has the support
for this. The following patch remedies this deficiency. Any proper integer
argument with no leading '%' is interpreted as a PID. The selected job is the
one which contains that PID. No other % semantics are changed. I haven't
tested it a whole lot, but it seems to work. The benefit is that you can do
things like "foo & disown $!". [ Just "disown" fails if for some reason "foo"
is not the "current" job. ] I just joined the list so forgive me if this is
already done or redundant in some other way.
