Bug#778648: devscripts: hitting ctrl-c while an editor is open should terminate bts, but instead it goes ahead

[Daniel Kahn Gillmor]

Package: devscripts
Version: 2.15.1
Severity: normal

emacs is my default editor.

it looks like if you send emacs a SIGINT, it will clean up nicely and
terminate with a return code of 0.

if i run a bts command that drops me into my editor in an X11
environment, emacs spawns as a separate window, while my shell is
blocked by the bts invocation (as it should be).

if i hit ctrl-C in the shell, though, apparently bts passes the SIGINT
through to my editor, and then proceeds to use the contents of the
message as prepared.

I expected ctrl-C to terminate the bts report rather than sending it
in.

here's me starting to close #770592 by mistake, realizing that wasn't
correct and trying to abort it:

0 dkg at alice:~$ bts done 770592 2.1.1-1
^C0 dkg at alice:~$

(the leading 0 in my prompt is the return code of the previous
command)

unfortunately, this actually did close #770592, which i didn't intend.
