In 73a834e9e2 ("range-diff: relieve callers of low-level configuration burden", 2018-07-22) we broke passing down options like --no-patch, --stat etc. Fix that regression, and add a test for some of these options being passed down.
As noted in a change leading up to this ("range-diff doc: add a section about output stability", 2018-11-07) the output is not meant to be stable. So this regression test will likely need to be tweaked once we get a "proper" --stat option.
See https://public-inbox.org/git/nycvar.QRO.7.76.6.1811071202480.39@tvgsbejvaqbjf.bet/ for a further explanation of the regression.
The quoting of "EOF" here mirrors that of an earlier test. Perhaps that should be fixed, but let's leave that up to a later cleanup change.
