cleanup whitespace and commas * [] is now [ ] * {} is now { } * commas in arglists go at end of line not beginning In short, I ran the whole thing through nixfmt-rfc-style but only accepted about 30% of its changes.

min-list-garbage: check all store paths against file this is step 1 of min-collect-garbage, no point implementing deletion ourselves when rm -r exists (arguably no point in implementing any of it, but this is the bit we can't do efficiently in bourne shell - it means we're reading the store-paths list once instead of grepping it afresh for every entry in /nix/store/) 2023-05-19 22:49:11 +00:00			`for i in min-copy-closure liminix-rebuild; do`
