Sure, no problem. I assume that since the 'module-tests' is implicit we
just have to check for the existence of f'{self.name}-tests'.

Yeah, that is the main reason that I wanted to look at it. You
implemented this after Paul wanted to use it for 'c99' [1]. I noticed
that one was very slow yesterday.

    $ time gnulib-tool --extract-recursive-dependents stdlib
    [...]
    real        0m52.093s
    user        0m10.577s
    sys         0m45.718s

    $ time gnulib-tool --extract-recursive-dependents c99
    [...]
    real        1m36.230s
    user        0m20.062s
    sys         1m24.070s
