Modified Files:
src/bin/sh: sh.1
Log Message:
Note in the description of "jobs -p" that the process id returned is
also the process group identifier (that's a requirement from POSIX, and
is what we have always done - just not been explicit about in sh.1).
Add a note that this value and $! are not necessarily the same (currently,
and perhaps forever, never the same in a pipeline with 2 or more elements).
