From systemctl(1)'s `show-environment`:
[...] If no special characters or
whitespace is present in the variable values, no escaping is
performed, and the assignments have the form "VARIABLE=value". If
whitespace or characters which have special meaning to the shell
are present, dollar-single-quote escaping is used, and assignments
have the form "VARIABLE=$'value'". [...]
`DISPLAY` is unlikely to require such escaping, but is still broken and
overly complicated.
Just rely on the fact that systemctl outputs line that are safe to be
interpreted by the shell.
Filter for `DISPLAY` and `eval` the output instead of trying to parse
just the value part and reassign it again.
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.

Allows setting `programs.obs-studio.package = null`, which is useful in
case the user wants the appropriate kernel modules from
`programs.obs-studio.enableVirtualCamera`, but does not wish to install
obs system-wide with nixos (e.g., because they want to install it just
for their user with home-manager or maybe via flatpak).
