The prohibit_nonreentrant syntax-check rule spawns a new shell for every non-reentrant function we know, to make it easier to mention the function name in the error message, with the _r appended. Since the line with the offending function is already printed and some of the functions on our list do not have a _r counterpart, compile them into one big regex and use a more generic error message to save time.
