full_str_pad() comes from a comment in the PHP manual for str_pad(). I 
realize that on php.net' manual, the comment is no longer intact but see 
here the original comment:

"In a lot of cases you're better off using str_repeat if you want to use 
something like   - it repeats the entire string."

So it look like there were (are ?) limits to what we can feed to 
str_pad() as the pad string.

In our case, however, we are using a null "\0" as the padding character; 
I tested it and it works in PHP 5.2.2 but I can't test right now with PHP 4.

There is still a problem when you use str_pad() to pad with a string 
like  

  echo str_pad('abc',100," ",1);

the result ends with the "&" character.
