Add a paragraph (briefer than previously posted to mailing lists)
to explain that there is no guarantee that the results of a command
substitution will be available before all commands started by the
cmdsub have completed.

Include the original proposed text (much longer) as *roff comments, so
it will at least be available to those who browse the man page sources.

While here, clean up the existing text about command substitutions to
make it a little more accurate (and to advise against using the `` form).
