PATCH (0.55 bug): Subroutine args incorrectly propagated to curscr

[Mark-Jason Dominus <mjd@xxxxxxxxxx>]

If you use the

	&function

syntax, with no explicit argument list, Perl propagates the current
contents of @_ to the function as its argument list..

This caused failures in ZigZag 0.55 when I pressed the control-R key.
For some reason, @_ was not empty, and was propagated to the curses
function `curscr', which would die with the message:

	Curses function 'curscr' called with too many arguments at (eval 21) line 1.
	        ...propagated at ./zigzag line 1888.
	        ...propagated at ./zigzag line 1903.

This patch fixes the bug.  I suggest that in the future the & syntax
be avoided.
