	ChangeLog
32540: in doexpandhist(), discard saved line position data rather than restoring from it (updates 32531).

32552 (updated by 32560): fix segfault when using process substitution in anonymous function argument list

Also disallow process substitution in function name position.

Affects for/select word lists, function definition name position, and
