Package:          Documentation problem
Bug Type:         Feature/Change Request
Bug description:crypt() should be documented as not binary safe

Description:
------------
http://www.php.net/manual/en/function.crypt.php

I understand that crypt() must not be binary safe in order to maintain 
compatibility with other implementations, but it should be clearly stated
in the 
crypt() documentation, since it might lead to unexpected results (for
example, 
when feeding raw bytes directly into crypt()).

Test script:
---------------
For example, this two lines generate the same output, which is correct, but
can be confusing:

echo crypt("aaa", '$2a$07$usesomesillystringforsalt$');
echo crypt("aaa\x00aa", '$2a$07$usesomesillystringforsalt$');
