getccu calls getchr which calls iread. When ctrl-Z (SIGTSTP) is entered, iread sets sigs |= S_STOP and returns READ_INTR. getchr then also returns READ_INTR. As of 2d0abe8, getccu converts any negative value like READ_INTR to a null char, which causes getccu to ignore the char and call getchr again. Before 2d0abe8 we would retain the negative char and exit the loop, but the char value was not used because the fact that sigs is set would be checked first. It seems more straightforward to just exit the getccu loop when sigs is set. Related to #563.

With less 643 and earlier, pressing Control-Z after running
