commit: YALF

[Martin Sevior]

The last of Thomas's UI improvements for lists. You can now delete a list
label and tab with a single backspace if you place the cursor after the
tab following the list label.

So if you press return in a list and you don't want the list label,
backspace and it is gone.

What will I do now? Oh all those bugs Paul Eagli found in Lists.

Cheers

Martin
