Even if we turn this "single"-liner composition of sentence into
interpolation (allowing for reordering of parts in translation),
like

   print colored $prompt_color, __x("{verb} {noun}{maybe_target} [y,n,q,a,d,/{other},?]? ",
   	verb => $patch_mode_flavour{VERB}, noun => $patch_mode_noun{$hunk[$ix]{TYPE}},
   	maybe_target => $patch_mode_flavour{TARGET} || "", other => $other);

This would of course require N__() on values of hash, somewhere.

the problem is that the ordering may need to change depending on
verb: "Stage", "Stash", "Unstage", "Apply", "Discard", and/or noun:
"mode change", "deletion", "this hunk", and/or presence and value
of maybe_target: " to index", " from worktree", " from index and worktree",
" to index and worktree".

Yes, this would be necessary; hide complexity behind helper function.
