[Quilt-dev] [PATCH] Fix interaction between quilt and vimdiff

[Jean Delvare]

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.

This is my attempt to fix:

I would love to have a more generic fix. Bert, can you think of one?
Is it possible to detect whether the diff viewer is interactive or
not and disable the pager on the fly if it is? I guess not :(
