Just minor changes like:
- Always using "X is a Y, but it should be Z"
- "X is a path that does not exist" rather than "X does not exist"
- Always using multi-line strings for errors
- Always quoting string-like values and not quoting path-like values
- But do quote filesystem roots. Even though they're paths, they might
be very small, good to have quotes to know the start/end
- Capitalise the first word
- Distinguish root vs filesystem root more
This does decrease performance unfortunately
Benchmarking expression toSource { root = ./.; fileset = ./.; }
Mean CPU time 0.103747 (σ = 0.012415) for 10 runs is 97.32181384964636% (σ = 16.34179537413021%) of the old value 0.106602 (σ = 0.0125571)

Statistic .values.number (275238) is 104.1199% (+10891) of the old value 264347
Currently just throws the Nix error because unknown file types are not
supported by the Nix store, but nothing catches this error earlier (yet,
see next commit)

We can now test returned paths being equal, no need to work around it
anymore by making sure paths aren't returned (which would import them
with the previous --json)
