As far as I understand the diffs, this problem occured first with commit
a75f557cc482d1753211634e8aac8b7572677015: The section about "Parallel
tests" had been inserted into the list about "Special Make Test Targets"
before the last "=item" of the list, but without an empty line between
the two of them.
The Great Revision of commit
04c692a854b61dfae1266e29468ce4fb51c80512
turned the "=item" about "Parallel tests" into a "=head2", leaving the
"=item" statement without the empty line in its old place.
There may have been some more editing in this corner. However, I
rearranged the lines, so that the "=item" statement goes with its original
list about the make test targets again.
nmake test TEST_FILES="op/*.t"
nmake test TEST_SWITCHES="-torture" TEST_FILES="op/*.t"
+=item * test-notty test_notty

+Sets PERL_SKIP_TTY_TEST to true before running normal test.

=head2 Parallel tests
Note that currently some test scripts may fail when run in parallel (most
notably C<ext/IO/t/io_dir.t>). If necessary, run just the failing scripts
again sequentially and see if the failures go away.
