zCobol compiles incur "actr limit exceeded" errors

This happens on fields defined as X(nnn) with an initial value that contains an ampersand character.
The logic is flawed: the ampersands in the literal need to be doubled up for the assembly to work okay,
but the added ampersand is coded as '&&' which still is two ampersands.
The additional ampersand caused macro WS.MAC to go into a loop.

Please fix the issue by unduplicating any literals inside the macro that contain incorrectly duplicated ampersands within a literal string.
