[physfs] Question regarding PHYSFS_getRealDir and PHYSFS_isDirectory

[Indy Sams]

Hello Eric,

	One thing I notice is you aren't including the directory in your call to PHYSFS_isDirectory in get_dir_listing().

	For example, you are using:
	PHYSFS_isDirectory("modules")
	instead of:
	PHYSFS_isDirectory("userdir/modules")

	The 2nd version should give you the results you are looking for.

ES>   get_dir_listing("/userdir");

ES> The output:
ES> real dir of /userdir/log: /home/estevens/.t-engine/3.0

ES> Contents of '/'
ES> Directory [game]
ES> Directory [game.mod1]
ES> File      [tome.cfg]
ES> File      [tree.txt]
ES> Directory [userdir]

ES> Contents of '/userdir' (all are directories)
ES> File      [log]
ES> File      [modules]
ES> File      [settings]
ES> File      [tmp]
