Silvan Mosberger 4f0dadbf38 treewide: format all inactive Nix files
After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.

Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.

A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

description = "Md5sum-alike program that works with Tiger/THEX hashes";
longDescription = ''
tthsum generates or checks TTH checksums (root of the THEX hash
tree). The Merkle Hash Tree, invented by Ralph Merkle, is a hash
construct that exhibits desirable properties for verifying the
integrity of files and file subranges in an incremental or
out-of-order fashion. tthsum uses the Tiger hash algorithm for
both the internal and the leaf nodes.
The specification of the Tiger hash algorithm is at:
http://www.cs.technion.ac.il/~biham/Reports/Tiger/
The specification of the THEX algorithm is at:
