Bug#717256: [checkbashisms] command -vV are erroneously marked as bashisms

[Olof Johansson]

Package: devscripts
Version: 2.12.6
Severity: normal
Tags: patch

Hi,

The checkbashisms script seems to erroneously mark 'command -v' and
'command -V' as bashisms. According to [1], these are well specified
flags (with the caveat: "On  systems  supporting  the  User
Portability Utilities option." (UP)), and indeed, supported by at least
bash, dash, zsh and busybox ash (posh on the other hand does not
support it).

While UP may be optional for strict POSIX conformity, Debian Policy
mandates that /bin/sh must implement SUSv3, where UP is a requirement
(if I understand correctly).

My proposed patch removes the check, and updates the unit tests to
make sure they are not reported as bashisms.
