--help text seems wrong for --dis/enable-nix

[jwaldmann]

cabal --help
...
 --enable-nix                   Enable Nix integration: run commands through
                                nix-shell if a 'shell.nix' file exists
 --disable-nix                  Disable Nix integration: run commands through
                                nix-shell if a 'shell.nix' file exists

in the second line, threre is a negation missing (don't run commands .. even if ..)?

cabal --version
cabal-install version 3.6.2.0
compiled using version 3.6.3.0 of the Cabal library

Thank you. Indeed, the code just repeats the description of the functionality after the colon, with no negation. It should probably add after the colon "if not disabled, it would...". I wonder if this can be worded in a natural, but precise way.

[jwaldmann]

my suggestion above was:

don't/never (?) run commands through nix-shell, even if a shell.nix file exists.

is that the correct semantics?

[Mikolaj]

I was being unclear. The code repeats the same description of the command for both the positive and negative case, only adding a different prefix. I think it's a good idea in general, but it sounds misleading at least in this case.
