Bart Schaefer 82ff9f24f1 48560: add TYPESET_TO_UNSET option to remove initialization of parameters
Changes typeset such that ${newparam-notset} yields "notset" and
"typeset -p newparam" does not show an assignment to the parameter.  This
is similar to the default behavior of bash and ksh, with minor differences
in typeset output.

Also add tests for some POSIX incompatibilities plus minor changes for test
harness robustness.
