Incorrect use of "expl" ?

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

Here's a list of all the completion functions that refer to the name
"expl" (usually by passing to _wanted or _requested, but sometimes by
e.g. "$expl[@]") without declaring it local.  Given that the name "expl"
is asserted only to be a convention, most of these are probably wrong.
