Log Message:
Modernise these (unused) functions

Much of what is here is truly ancient.   It isn't used as
part of the build (never installed anywhere) so are only
available from src/bin/sh/funcs which means that in practice
no-one ever sees or uses any of this.

A notable example is the provided 'suspend' function, which
has been using "set +j" to turn off job control all this time.
That was the old (original ash) name for what is now the 'm'
option ... it was changed (by Berkeley CSRG) in July 1992
(approaching 33 years ago), which means the suspend function
provided here hasn't been used in at least 33 years.
(Since "suspend" is now provided as a sh builtin, the function
here is no real use anyway).

Still, since they exist here, they may as well be made to work
properly.

Note: should anyone decide to install these somewhere, the
"pushd" "popd" and "dirs" scripts are all the same thing,
and (while they could be installed as 3 files) should really
be just one file, linked to 3 names, when installed - it
makes no practical difference which of them gets copied rather
than just being a link.
