Before, make accepted misspellings like .warnings, .export-literally and
a few others, all of which are unlikely to occur in practice. See the
test directive-misspellings.mk for further details.
The test names have been derived from the current manual page.
All these tests are dummies right now, and the code from the existing
tests will be moved into the new tests step by step.
This is done to prevent modmisc, escape, varmod-edge and varmisc from
growing without any bounds, and to reduce the side-effects of one test
to the others.
