[Mourty]

Recent changes in the "…" menu was a side menu that opened on hover. The "…" menu sits at the window's right edge, so there was no room on the right and the side menu opened over the menu itself. Moving the pointer down past it to Export or Preferences covered them for a while.

It now unfolds in place when clicked:

• Newest first. At most about ten changes tall, and no more than 40% of the screen. The rest scroll, so even the full hundred keeps the menu a sensible size.
• A fixed width. A long name is cut with "…" and shown whole on hover, instead of widening the menu. The times line up on the right as before.
• Folded and at the top each time the menu opens, so the menu stays short until you ask for the list.
• Clicking a change undoes back to before it and closes the menu, as before.

The "…" menu now closes only on a click outside it or on an item, like the strip and bus menus, so the click that unfolds the list doesn't close it. Every item closes the menu itself. The list's items name the menu when closing it (close_kind), because a plain close() closed the fold around them instead.

The user guide's Undo section says how it works now.

Tested

• clippy is clean and the window's tests pass.
• Under Xvfb with 60 changes in the history:
  • the list unfolds and scrolls;
  • a long name is cut and shown whole on hover;
  • reopening the menu shows the list folded, and unfolded it starts at the newest change;
  • picking the third change undid three and closed the menu.
