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 :

What else does `debug_print_backtrace()` include? If the info is more maybe 
we should change `debug_backtrace()`?
In any case, in general I don't have a problem to do this. Might be nicer 
if we could do it without output buffering though but I haven't looked at 
the code to see how hard that would be.
