Diff LGTM. Overall in favor of this change. fish_config with Python disabled fails, as expected.
EDIT: Closure goes from 190.3M to 125.5M with Python disabled, according to nix path-info -Sh ./result.

Python is still used for tests, but does not become part of the closure. In addition, nowadays fish only ever uses Python via __fish_anypython, so using sed or propagating python isn't necessary anymore.

Motivation for this change
Fish needs Python only for generating completions from man pages and the web config editor, so people may want to avoid depending on it. Even without depending on Python, the functions can still be called by adding Python to
$PATH(using e.g.nix-shell). The package still depends on Python by default.Notes
These days fish only uses the
__fish_anypthonfunction to find an interpreter to use, so using sed or propagating python isn't necessary anymore.cc @adisbladis
