strendzap removes pat from the end of str if it is there.  Otherwise, it does nothing.

       To remove the suffix .c from the end of a filename, you might do this:

            #include <publib.h>

            strendzap(filename, ".c");

strendzap returns non-zero if it removed anything, 0 if not.
