Re: [PATCH v4 8/7] wildmatch test: skip file creation tests on Windows proper

Ævar Arnfjörð Bjarmason [off-list ref] writes:

I agree that there should be some prerequisite to skip this on Windows
by default since 6 minutes is clearly excessive (although I think you'll
find it runs a bit faster in the branch above), but that should be
something like:

    test_lazy_prereq EXPENSIVE_ON_WINDOWS '
            test -n "$GIT_TEST_LONG" || test_have_prereq !MINGW,!CYGWIN
    '

As the long runtime is not inherent to the test, but to excessive
slowness caused by certain operations on certain platforms, or maybe it
should be EXPENSIVE_ON_SLOW_FS or EXPENSIVE_IF_FORKING_IS_SLOW or if
we'd like to generalize it.

We already do skip overly long tests everywhere unless explicitly
asked to run them, and the above sounds like a good way to go.
