Bug#968742: diffoscope build-depends on package that is not in testing.

[peter green]

Package: diffoscope
Version: 156
Severity: serious

Diffoscope has been removed from testing and cannot re-enter because it build-depends on
gnumeric, which has been kicked out of testing due to a python2 dependency.

Since this build-dependency only appears to be used for testing I would suggest dropping it
until/unless gnumeric is fixed.
