Bug#849465: bts version: check arguments

[積丹尼 Dan Jacobson]

Package: devscripts
Version: 2.16.13
Severity: wishlist
File: /usr/bin/bts

Perhaps check if the user has given extra arguments to version, and at
least return non-zero.

$ bts version 999999 1.2.3; echo $?
bts version 2.16.13

That way programs that use "version" instead of the intended "found"
would find out earlier.
