Description:
------------
considering the current implementation of php_cgi_ini_activate_user_config in cgi_main.c, .user.ini will never be read if the current working equals DOCUMENT_ROOT:

<code>
ptr = s2 + start;  /* start is the point where doc_root ends! */

/* the following condition will never be true, because ptr points to the last character of the directory name (see above), which is, by implementation, no DEFAULT_SLASH. */
while ((ptr = strchr(ptr, DEFAULT_SLASH)) != NULL) { /*...*/ }

</code>

Expected result:
----------------
.user.ini will be read, if it is stored in DOCUMENT_ROOT, or in the runtime folder of the application server (i.e. php-cgi), no matter if both folders are identical.

Actual result:
--------------
If .user.ini is stored in DOCUMENT_ROOT, and your application server has DOCUMENT_ROOT as runtime folder, then .user.ini will not be read.

If you change DOCUMENT_ROOT to something invalid, and make the application server run in the folder where .user.ini is stored, then .user.ini will be read.
