moving to ext/ and importing differently was actually the way to be more
sure to use in source init files.  But the tests need to be called with
--epub3 and HTML_MATH, I didn't make that change systematically, will
do.  However this won't solve the case of tests using init files that
are not considered as being internal extensions.  It should be possible,
however, to set differently include directories when TEST is set.  I'll
see what I can do if you don't do it first.
