It would be horribly broken if it did, but it doesn't (applied
directly to echo ksh does exactly what it should do).
The question is this part (2.9.5) ...
When a function is executed, it shall have the syntax-error and
variable-assignment properties described for special built-in
The "variable assignment properties described for special built-in
utilities" means (or includes) the (now) oft quoted sentence from 2.14,
that "Variable assignments specified with special built-in utilities
remain in effect ...".
That's what NetBSD's shell does not do (and ksh does). But please
note, this is not a bug report, I want the NetBSD shell to remain the
way it is, the SUS version (and ksh) is just plain brain dead.
