Tab closed via `tabc n` cannot be undo.

When close a tab with tab n, where n is the tab number to be close, then <c-w>c won't works.

The plugin can only work with :quit and ZZ, and potentially any other keybindings that close a window while triggering the QuitPre event. Unfortunately, tabclose doesn't do that, so tab information can't be detected and stored. There's more explanations in the discussion in https://github.com/AndrewRadev/undoquit.vim/issues/10.

I've implemented a workaround of sorts -- the plugin now provides an :UndoableTabclose command that should work the same way as the bulit-in :tabclose. You could map it to something and use that instead. I realize it's inconvenient, but there's nothing I can do to support tabclose n, at least as far as I know.

You can see the details of how this works in the updated documentation. Could you try it out and let me know what you think?

Got it, thanks.
