/commands says what each word does, and that the root's ctl takes Edit

A /commands line gave a word, its argument and root or pane, but not
what it does, and called Edit a pane's word though the root's ctl takes
it too. Each line now ends with -- and the first sentence of the word's
doc comment (read from builtins.zig itself, so there is one copy), and
Edit is both. fs.md says a pane's word such as Undo or Msg is refused at
the root.
