Yes, this looks like a bug. I have just added it to the bug list at 
SourceForge.

No, you are correct that there's no way to get a handle on the current 
redo command. Jeroen has addressed this problem in the FOX 1.2 version 
of FXUndoList, so in the interest of (future) API compatibility, I 
think I'll add two new methods:

* FXUndoList#undoName returns the text of the current undo command (or 
nil if there is none)
* FXUndoList#redoName returns the same for the current redo command.

How does that sound?
