[New-bugs-announce] [issue16887] IDLE - tabify/untabify applied when clicking Cancel

[Roger Serwy]

New submission from Roger Serwy:

Krystian Rosiński notified me about an error with Tabify/Untabify. Clicking cancel still performs the operation because the _asktabwidth function in Lib/idlelib/EditorWindow.py always returns a number, regardless of cancel being clicked.

This bug is visibly noticeable with IdleX since it highlights all \t Tabs, but not with the original IDLE.

The attached patch solves the problem.
