A tag no longer marks an unsaved file with *: the grip shows it

The grip button now shows a pane's unsaved text in every state, as acme's modbutton does, and acme's tag has no asterisk. The computed prefix is the name alone, so tag reads, event offsets that count the path and the tag's text lose the " *". dirty, index's flag and the refuse-once guards are unchanged; a dump from before still restores its tags past the old mark.

 Save is marked at ask-time rather than on completion because `save_file`
 carries none back, which makes both indicators exactly as honest as the Save
 request.
