Bug#832147: debdiff: return value doesn't match man page

[Martin Michlmayr]

Package: devscripts
Version: 2.16.4
User: devscripts at packages.debian.org
Usertags: debdiff

I get a return value of 2 when runnning debdiff on files that don't
exist:

66076:tbm at loric-alpo: ~] debdiff a b ; echo $?
debdiff: fatal error at line 354:
Can't read file: a
zsh: exit 2     debdiff a b
2

But debdiff(1) says:

Normally the exit value will be 0 if no differences are reported and 1
if any are reported.  If there is some fatal error, the exit code will
be 255.
