style parameter markers to something more appropriate, if the driver
supports one style but not the other.

<simpara>
As of PHP 5.3.0, the parser used for emulated prepared statements and for
rewriting named or question mark style parameters supports the non standard
backslash escapes for single- and double quotes. That means that terminating
quotes immediately preceeded by a backslash are not recognized as such, which
may result in wrong detection of parameters causing the prepared statement to
fail when it is executed. A work-around is to not use emulated prepares for
such SQL queries, and to avoid rewriting of parameters by using a parameter style
which is natively supported by the driver.
