Description:
------------
Documentation says that on *nix systems open_basedir paths must be separated by 
colon characters, but it does not say if it is possible and how to include a path 
containing an actual colon (which is a perfectly valid path on linux, for 
example).

How can I add /foo:bar to open_basedir?

Expected result:
----------------
I should be able to know if and how to escape the separator colon, for example 
with
open_basedir = /www\:80:/somewhere_else
to add the two directories '/www:80' and'/somewhere_else'.

Documentation should tell me I cannot use colons in paths, or tell me how I can 
use them.

(besides, if there isn't any escape possibility it should be added IMHO)

Actual result:
--------------
Adding a path with a colon inside gets interpreted as two different paths.
Official documentation does not help on the matter.

Can you please test that escaping mechanism? Maybe you could also test it within 
PATH itself

I was just giving an example. Anyway I did actually try to escape colons with 
backslashes, and I re-tried now on PHP 5.3.15, without success.

Additionally, if you have colons in intermediate elements of a path, like this:
  /www/foo:80/bar
and you specify an open_basedir like "/www" or "/www/", PHP will block any access 
to the above path.

Unfortunately I cannot, at the moment, test this on recent versions of PHP and/or 
ones without Suhosin installed, but it does replicate perfectly on my PHP-
5.3.15+Suhosin-0.9.33 system.
