3 # Test for parsing a .for loop that accidentally contains a null byte.
4 #
5 # As of 2020-12-19, there are 3 error messages:
6 #
7 # make: "(stdin)" line 2: Zero byte read from file
8 # make: "(stdin)" line 2: Unexpected end of file in for loop.
9 # make: "(stdin)" line 3: Zero byte read from file
10 #
11 # The one about "end of file" might be misleading but is due to the
12 # implementation. On both errors and EOF, ParseRawLine returns NULL.
13 #
14 # The one about the "zero byte" in line 3 is surprising since the only
15 # line that contains a null byte is line 2.
