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 install_test_db
and mysql-test-run.  This patch also improves the documentation a tad.

 the currently existing test cases, simply execute ./mysql-test-run in

+For use in Red Hat distributions, you should run the script as user mysql,

+	cd /usr/share/mysql-test
+	sudo -u mysql ./mysql-test-run
+This will use the installed mysql executables, but will run a private copy

 If you want to run a test with a running MySQL server use the --extern
 option to mysql-test-run. Please note that in this mode the test suite
 expects user to specify test names to run. Otherwise it falls back to the
-normal "non-extern" behaviour. The reason is that some tests
-could not run with external server. Here is the sample command
