d946f22a4c 44664: Fix problem with temporary assignment. 
"foo=bar builtin" inside a function lost any variable from
enclosing scope.

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.

f99f7dca75 43616: Various parameter setting and display fixes. 
Mostly to do with typeset -p and tied variables and their interaction.

Some general tied variable fixes.

85b0dd7133 Updates for ksh array element syntax. 
Move detection of key/value pairs down into prefork().

Detect normal array assignment and [key]=val array assignemnt
separately.  Mark key / value pairs with Marker and pass up flag.  Deal
with marked triads specially later on.

54b3958440 First go at var=([key]=value) syntax. 
Works for both normal and typeset case, also var+=...

Still to do: allow to be mixed with straight array assignment,
improve typeset -p, implement [key]+=value.

a2e2f5668d 40990: Fix crash with bogus path in sh emaulation. 
When startying in sh emulation don't link PATH-style parameters
to array equivalents.  To allow this to function, don't check
for the linkage when exporting the colon-separated parameter.

ab81b98c49 39758: revise 39704 for array and hash parameters; more POSIXBUITINS tweaks for 
export

39704 was commit 0f5e670, forgot to reference article number in that log.

"typeset -p" outputs "typeset" for array and hash parameters, even when
exported, because those types can be marked export but are never pushed
to the enviroment.

For POSIXBUILTINS, "export var" does not implicitly set $var, and its
export state is preserved when assigned (but not when explicitly unset).
