/* TODO:
 * - test the default verb selection

 * - ShellExecute("foo.shlexec") with no path should work if foo.shlexec is
 *   in the PATH
 * - test associations that use %l, %L or "%1" instead of %1
 * - we may want to test ShellExecuteEx() instead of ShellExecute()
 *   and then we could also check its return value
 * - ShellExecuteEx() also calls SetLastError() with meaningful values which
