See also the recent thread I started
https://public-inbox.org/git/87sgwav8cp.fsf@evledraar.gmail.com/ asking
if these wrappers were useless now. The consensus was to keep them (a
bunch of use-cases I didn't know about). Useful if you're poking at them
and wondering why we're using this / what it gives us.

Interesting that for some we use the 'test_is_there/test_is_not_there'
pattern and for others 'test_is_there [!]'. E.g
test_path_exist/test_path_is_missing v.s. test_i18ngrep.
