Sorry colder, I didn't realise you were already working on
this, go ahead.

The note is not completely wrong. If the array contains an element that
is === false, there is no way to properly distinguish it from the
beginning/end of the array.

This also affects the manual page for prev() and next().

This patch should help you a bit:

Description:
------------
There is a warning box on the documentation for the current()
function.

It talks about the impossibility of differing between the end of the
array and the value zero or "". It is possible to use current() with
these values using the === operator.

The real problem is arrays containing the value false, this isn't
actually mentioned in the warning.

Further the warning suggests using each() instead of current() to get
around these problems, however the two functions aren't really
comparable as each() advances the array cursor.
