Bug#274383: fix for the scratch bug

[San Vu-Ngoc <san.vu-ngoc@laposte.net>]

I found out it is easy to fix this bug from the source package.
in the file "scratch.ml", line 382, add:
   | 'q' -> end_draw ()
   | '\027' -> end_draw ()


and recompile. Too bad I don't know how to generate a new debian package 
with this.
