COM_CHANGE_USER/mysql_change_user() cleans up the line. The call itself 
exists since quite some time. In its early days (say more than three 
years ago) it was known to have issues. But its working fine nowadays.

Its possible to clean up the line before reuse, if wanted. Calling 
mysql_change_user is the default for ext/mysqli. However, if you know 
what you do, you may not want to clean the line for performance reasons.
