mysql's idea of a suitable place to install the regression tests is
/usr/mysql-test.  To relocate this to a reasonably FHS-compliant place
like /usr/share/mysql-test, we have to hack up the paths in mtr_cases.pm.
This patch also improves the documentation a tad.

 to the normal "non-extern" behavior. The reason for this is that some
