Description:
------------
It looks like between 5.6 and 7.0 somebody broke the CLI utility's `-R` option. Specifically:

* $argi is always 0

* $argn always has the last character cut off

I've confirmed it works as expected in PHP 5.6.14 on OS X, whilst it's broken in 7.0.2 on OS X and master on Ubuntu.

I'm not very good at C, so i don't have a patch, i'm sorry.

Test script:
---------------
% php -R 'echo "${argi}\n";' <<< $'foo\nbar'
% php -R 'echo "${argn}\n";' <<< $'foo\nbar'

Expected result:
----------------
% php --version | head -1
PHP 5.6.14 (cli) (built: Oct  3 2015 14:54:13)
% php -R 'echo "${argi}\n";' <<< $'foo\nbar'
1
2
% php -R 'echo "${argn}\n";' <<< $'foo\nbar'
foo
bar

Actual result:
--------------
% php --version | head -1
PHP 7.0.2 (cli) (built: Jan  7 2016 10:40:26) ( NTS )
proserpina:php % php -R 'echo "${argi}\n";' <<< $'foo\nbar'
0
0
proserpina:php % php -R 'echo "${argn}\n";' <<< $'foo\nbar'
