doc weird aligning and double text and missing information

[flip111]

consider:

>>> doc array_reduce
function array_reduce($arg, $callback, $initial = unknown)

Description:
  Iteratively reduce the array to a single value using a callback function

  array_reduce applies iteratively the callback function to the elements of the array, so as
  to reduce the array to a single value.

Param:
  array     $array     The input array.
  callable  $callback  Holds the return value of the previous iteration; in the case of the first
                       iteration it instead holds the value of initial.

                       Holds the value of the current iteration.
  mixed     $carry     Holds the return value of the previous iteration; in the case of the first
                       iteration it instead holds the value of initial.
  mixed     $item      Holds the value of the current iteration.
  mixed     $initial   If the optional initial is available, it will be used at the beginning of
                       the process, or as a final result in case the array is empty.

Return:
  mixed  Returns the resulting value.

         If the array is empty and initial is not passed, array_reduce returns null.

Reference: http://php.net/manual/en/function.array-reduce.php

problem 1: $carry and $item are idented on the php website, but not in psysh
problem 2: double sentences such as Holds the value of the current iteration
problem 3: missing information function header mixed callback ( mixed $carry , mixed $item )

Good catch. I'll take a look at it and see if I can get it to make sense.

Update: the fix for this is actually quite a bit of work. I've got an initial shot at it, but it's not all fixed just yet. Sorry about the delay.
