Edit written to /tagexec or a column's exec is refused as the other pane words are

Edit was let through the pane-word check (the root's ctl takes it at the
active pane), so `Edit ,d` written to a tag no pane owns wiped the pane
with the keyboard. Every pane-scope word a tag does not hold is refused
there now, Edit included; a test enumerates them all.
