Module Name:    src
Committed By:   kre
Date:           Thu Aug 20 23:19:34 UTC 2020

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

Log Message:
Man page enhancements.

Better describe the command search procedure.
Document "trap -P"
Describe what works as a function name.
More accurate description of reserved word recognition.
Be more accurate about when field splittng happens after
expansions (and in particular note that tilde expansions are
not subject to field splitting).   Be clear that "$@" is
not field split, it simply produces multiple fields as part
of its expansion (hence IFS is irrelevant to this), but if
used as $@ (unquoted) each field produced is potentially subject
to field splitting.   Other minor wording changes.
