Description:
------------
Hello,

Functions rollback() works fine expected that
the return value is inverted.

if rollback() failed, return value is TRUE,
if rollback() success, return value is FALSE.

The problem is that the Documentation say the opposite.

So for my code work fine, I've to write:

if( $dbh1->rollback() ){
 printf( "DBH1 Failed to rollback : %s \n", $dbh1->error);
}

bye

Reproduce code:
---------------
if( $dbh1->rollback() ){
 printf( "DBH1 Failed to rollback : %s \n", $dbh1->error);
}


Expected result:
----------------
if( ! $dbh1->rollback() ){
 printf( "DBH1 Failed to rollback : %s \n", $dbh1->error);
}
or
if( $dbh1->rollback() == FALSE ){
 printf( "DBH1 Failed to rollback : %s \n", $dbh1->error);
}
