Log: fix bug 55562 - make substr always return rest of the string if length is 
too long

I can confirm this bug, but I'm not sure how to fix it correctly. If I fix the 
related logic, the substr tests then partially fail. This function is cryptic 
and 
should really deserve some comments about what means each variable name and 
what 
are their goals...

Description:
------------
If the input string contains multibyte characters and the length argument is 
greater then the possible maximum length of the result the function returns 
false.

Test script:
---------------
<?php
var_dump(
  grapheme_substr('FOK', 1, 20), // expected: OK
  grapheme_substr('한국어', 1, 20) //expected: 국어
);

Expected result:
----------------
string(2) "OK"
string(6) "국어"

Actual result:
--------------
string(2) "OK"
bool(false)
