Bug description: wrong detection of 'data' wrapper causes notice
Description:
------------
On NetWare we have volume names similar to drive letters on Win32;
however the volume names are not just one char, but can be up to 16 chars,
so an valid absolute path can look like:
data1:/myfolder/otherfolder
Now if I use f.e. is_dir(data1:/myfolder/otherfolder) then I get:
Notice: is_file() [function.is-file]: Unable to find the wrapper "data1" -
did you forget to enable it when you configured PHP? in
data1:/web/project/tstpaths.php on line 13
It seems to me that the problem is in ./main/streams/streams.c at line
1519; I did modify this line as below, and the issue is then gone:

path, 4))) {

protocol = path;
} else if (n == 5 && strncasecmp(path, "zlib:", 5) == 0) {
/* BC with older php scripts and zlib wrapper */
however I'm not sure if now the 'data' wrapper still works; but formerly
due to the '||' everything beginning with 'data' did match.
I cant see a reason why the test for 'data' has to be handled without
checking for '://', but then I'm not familar with the 'data' wrapper at
all.
Reproduce code:
---------------
<pre>
<?php
// Test for the 'data' wrapper bug.
ini_set('display_errors', 1);
ini_set('error_reporting', E_ALL);
$mydir = "data:/myfolder/another/folder";
echo "is_dir ( $mydir ) = " . (is_dir($mydir) ? "true" : "false") . "\n";
$mydir = "data1:/myfolder/another/folder";
echo "is_dir ( $mydir ) = " . (is_dir($mydir) ? "true" : "false") . "\n";
$mydir = "data2:/myfolder/another/folder";
echo "is_dir ( $mydir ) = " . (is_dir($mydir) ? "true" : "false") . "\n";
?>
<pre>
Expected result:
----------------
is_dir ( data:/myfolder/another/folder ) = false
is_dir ( data1:/myfolder/another/folder ) = false
is_dir ( data2:/myfolder/another/folder ) = false
Actual result:
--------------
is_dir ( data:/myfolder/another/folder ) = false
