Description:
------------
Today, glob() calls the libc glob() function, with the following problems:

- Possible inconsistencies between implementations (POSIX compliance)

- fnmatch not available outside of Unix : an internal glob() implementation would bring an internal fnmatch() implementation, which would allow fnmatch() on every platform.

- Important: on most (every ?) Unix systems, glob() is using stat() instead of lstat(). Thus, broken links are ignored. Inconsistant with a naive 'ls' which lists everything in the directory.

- The current glob() implementation in PHP (ext/standard/dir.c) assumes that all returned matches are in the same directory, which is wrong. So, the 'safe mode' and 'open_basedir' checks are wrong.

- glob() does not support streams, although most other directory functions support them. It cannot be done without implementing glob() internally.

- Apart from glob(), the chdir() and getcwd() functions should also support stream-wrapped directories. It would be easy to implement but it must be synchronized with the support of stream wrapped paths in the include path.
