both are done by intention

I used "pre-increment" at --$c; because it's faster than post-increment: 
http://www.tuxradar.com/practicalphp/18/1/8
and this is a speed critical function.

concerning "assignments in conditions" CGL says:

"Assignment in conditions should be avoided. However if it makes sense 
to do assignment in condition, it should be surrounded by the extra pair 
of brackets. Example:
	if (($fields = $GLOBALS['TYPO3_DB']->sql_fetch_result($res))) {
		// Do something
	}
"
