Subject: Fix interaction between quilt and vimdiff
References: bnc#749563

Using vimdiff as a diff viewer in quilt breaks if QUILT_PAGER is set.
So inhibit the pager in that case. Other diff viewers may be affected
as well but I don't know how to fix this in a generic way, short of
inhibiting the pager as soon as option --diff is passed to the diff
command. Not sure if this desirable though, as I presume
non-interactive alternative diff viewers must exist too.
