description:
Add a new sub-test to validate ~ expansions.

Currently testing ~user is too much effort to contemplate (other than
assuming that it works in order to verify that it works...) so only bare ~
is being tested for now.   Maybe someday...

Right now (@ time of commit), this new test is expected to fail, as ~
expansions are horribly badly broken (have been for months, some forms
for much longer) in all but the simplest of uses.   Fix for that coming
very soon.
