Very long lines not formatted.

{python = pkgs.python3.withPackages (ps: [rmt-utilities] ++ (with ps; [bunch codecov coverage docutils flake8 ipython matplotlib numpydoc sphinx-copybutton sphinx_rtd_theme sphinx-autoapi sphinx-argparse sphinx twine versioneer]));}

leaves it unchanged:

Congratulations! Your code complies with the Alejandra style.

👏 Special thanks to Daniel Salazar for being a sponsor of Alejandra!

However if you split it anywhere inside the second list, e.g.

{python = pkgs.python3.withPackages (ps: [rmt-utilities] ++ (with ps; [bunch codecov coverage docutils flake8 ipython matplotlib numpydoc sphinx-copybutton sphinx_rtd_theme sphinx-autoapi sphinx-argparse sphinx twine versioneer
]));}

it formats it nicely:

{
  python = pkgs.python3.withPackages (ps:
    [rmt-utilities]
    ++ (with ps; [
      bunch
      codecov
      coverage
      docutils
      flake8
      ipython
      matplotlib
      numpydoc
      sphinx-copybutton
      sphinx_rtd_theme
      sphinx-autoapi
      sphinx-argparse
      sphinx
      twine
      versioneer
    ]));
}

Splitting it in other places though, like

{python = pkgs.python3.withPackages (ps: [rmt-utilities
] ++ (with ps; [bunch codecov coverage docutils flake8 ipython matplotlib numpydoc sphinx-copybutton sphinx_rtd_theme sphinx-autoapi sphinx-argparse sphinx twine versioneer]));}

still leaves it with a particularly long line

{
  python = pkgs.python3.withPackages (ps:
    [
      rmt-utilities
    ]
    ++ (with ps; [bunch codecov coverage docutils flake8 ipython matplotlib numpydoc sphinx-copybutton sphinx_rtd_theme sphinx-autoapi sphinx-argparse sphinx twine versioneer]));
}

While this particular file is just one line, I found this issue when I put that exact line into a larger flake.nix file so it's nothing to do with it just being one line.
