Description

Erasing characters at the conflict prompt does not seem to work anymore.

The prompt looks as follows after hitting p, then backspace, and then the delete
key::

$ svn resolve 
Conflict discovered in file 'alpha'.
Select: (p) postpone, (df) diff-full, (e) edit, (m) merge,
        (mc) mine-conflict, (tc) theirs-conflict, (s) show all options: p^?^[[3~

It seems the new terminal prompt support code is responsible for this.
Enabling canonical input mode fixes the problem, but reintroduces the
cancellation problem fixed in r1439093.

Can we somehow fix the backspace key while allowing quick cancellation?
