stuebinm 6afb255d97 nixos: remove all uses of lib.mdDoc
these changes were generated with nixq 0.0.2, by running

  nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
  nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
  nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix

two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.

Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.

description = ''
Configuration from which XMonad gets compiled. If no value is
specified, a vanilla xmonad binary is put in PATH, which will
attempt to recompile and exec your xmonad config from $HOME/.xmonad.
This setup is then analogous to other (non-NixOS) linux distributions.
If you do set this option, you likely want to use "launch" as your
entry point for xmonad (as in the example), to avoid xmonad's
recompilation logic on startup. Doing so will render the default
"mod+q" restart key binding dysfunctional though, because that attempts
to call your binary with the "--restart" command line option, unless
you implement that yourself. You way mant to bind "mod+q" to
`(restart "xmonad" True)` instead, which will just restart
xmonad from PATH. This allows e.g. switching to the new xmonad binary
after rebuilding your system with nixos-rebuild.
For the same reason, ghc is not added to the environment when this
option is set, unless {option}`enableConfiguredRecompile` is
set to `true`.
If you actually want to run xmonad with a config specified here, but
also be able to recompile and restart it from a copy of that source in
$HOME/.xmonad on the fly, set {option}`enableConfiguredRecompile`
to `true` and implement something like "compileRestart"
from the example.
This should allow you to switch at will between the local xmonad and
the one NixOS puts in your PATH.
