"Register a formatter to `apheleia''s lists.
NAME is the name given to the formatter in `apheleia-formatters'
and `apheleia-mode-alist'. FORMATTER is the command paired with
NAME in `apheleia-formatters'. MODE is the mode or modes to add
NAME to in `apheleia-mode-alist'. If MODE is not given or nil,
use the setup form's MODE. Optional argument -PEND can be one of
`:append' or `:prepend', and if given will append or prepend the
given NAME to the current formatters for the MODE in
`apheleia-mode-alist', rather than replace them (the default).
Example:
(setup
(:apheleia isort (\"isort\" \"--stdout\" \"-\")
python-mode))
; =>
(progn
(setf (alist-get 'isort apheleia-formatters)
'(\"isort\" \"--stdout\" \"-\"))
(setf (alist-get 'python-mode apheleia-mode-alist)
'isort))
This form cannot be repeated, and it cannot be used as HEAD.")
