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, ParseGetLine 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.
