baa19d2a85 51945: assorted documentation improvements, bug fixes, and new test 
1) Document the behavior of "typeset -n existing_var" (via Jun T. comment)

5) Allow "typeset +r -n ref" and "typeset +r +n ref" (Jun T.)
6) Fix "typeset -r -n ref=param" to create readonly references
7) Avoid accidental removal of PM_UNSET flag (Jun T.) and update test
8) Fix "typeset -gn ref=value" and add a test for it
9) Add tests for read-only reference behavior
10) Fix infinite recursion when resolving scope of an unset local
named reference, add test.

32cceefa95 51437: Fix incorrectly-passed test case, masked by unrelated bug. 
A bug with zmodload when unloading/reloading a static module caused the
state of the shell options to change during K01 test.  Worked around it.
Also changed warnnestedvar messages to look more like other such.

Bart Schaefer
3eed6f70cd 51402: Some ksh/bash features, additional sanity checking 
* Add "unset -n"
* Allow and enforce "typeset -n -r" for read-only references
* "can't change type via subscript reference" error
* Better checking for self-referential declarations/assignments
* Ksh-style "foo=bar; typeset -n foo" creates foo=bar reference
* Support "typeset -n ref; for ref in ..."
* Subscripted references use NO_EXEC for safety
* References assigned in called scopes reset scope at end
* Allow named references to $! $? $$ $- $0 $_

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.

8cbbc04d97 44509: Prevent crash with modified path / PATH combination. 
Crash came from "fn() { typeset -U path=($path); unset PATH; }".

Note PATH unset is global as only path was made local.
