Files containg checksums doesn't contain file names

The files containing the SHA256 checksums should contain the file names after the checksum. E.g. the current checksum file for Graphical live CD, 64-bit Intel/AMD should contain the following

1bcd44d8b2c60a18a39a60dcf80c50b230ab24950130dddacc0b5ed12718e369 nixos-graphical-18.03.132618.0f73fef53a9-x86_64-linux.iso

The reason why the file should contain the file name is to enable users to verify the checksum easily with the command sha256 -c [file].iso.sha256.

Where this seems to happen:

• https://github.com/NixOS/nixos-channel-scripts/blob/9f96e1e25d197de46d5dbe3c4f81b8d57b9c9821/mirror-nixos-branch.pl#L109-L115

The manpage says:

The sums are computed as described in FIPS-180-2. When checking, the input should be a former
output of this program. The default mode is to print a line with checksum, a space, a character
indicating input mode ('*' for binary, ' ' for text or where binary is insignificant), and name
for each FILE.

So it looks like write_file("$dstFile.sha256", "$sha256_expected $dstFile"); (two spaces) could work?

EDIT : github markdown ate a space inside the <code> block beforehand!
