Optional parameter for debug_print_backtrace()

Hi internals, what do you think about adding an optional parameter to debug_print_backtrace() (PHP 5 only) so instead of printing the stacktrace to get it as string. The information provided by debug_print_backtrace() is more than the information provided by debug_backtrace(). So if the parameter is added the function will behave just like print_r() which has second optional parameter. I have made a patch which is available here : http://hristov.com/andrey/projects/php_stuff/patches/debug_print_backtrace_as_string.diff.txt Andrey
