Upstream patch to fix "md5sum --check --ignore-missing" which treated
files with checksums starting with "00" as missing.
To be removed with coreutils > v8.25.
Test case illustrating the issue:
$ echo 559 > file
$ md5sum file | tee file.md5
000b64c5d808b7ae98718d6a191325b7 file
With the file being intact, md5sum previously issued a misleading error
diagnostic, and returned with exit code 1.
$ md5sum -c --ignore-missing file.md5; echo $?
md5sum: file.md5: no file was verified
1
With the file being changed, md5sum still detected the changed file ("FAILED"),
but still stated that the file was not checked; at least the exit code was okay.
$ echo tampered >> file
$ md5sum -c --ignore-missing file.md5; echo $?
file: FAILED
md5sum: WARNING: 1 computed checksum did NOT match
md5sum: file.md5: no file was verified
1
