readdirex({directory} [, {expr} [, {dict}]])			*readdirex()*
		Extended version of |readdir()|.
		Return a list of Dictionaries with file and directory
		information in {directory}.
		This is useful if you want to get the attributes of file and
		directory at the same time as getting a list of a directory.
		This is much faster than calling |readdir()| then calling
		|getfperm()|, |getfsize()|, |getftime()| and |getftype()| for
		each file and directory especially on MS-Windows.
		The list will by default be sorted by name (case sensitive),
		the sorting can be changed by using the optional {dict}
		argument, see |readdir()|.

		The Dictionary for file and directory information has the
		following items:
			group	Group name of the entry. (Only on Unix)
			name	Name of the entry.
			perm	Permissions of the entry. See |getfperm()|.
			size	Size of the entry. See |getfsize()|.
			time	Timestamp of the entry. See |getftime()|.
			type	Type of the entry.
				On Unix, almost same as |getftype()| except:
				    Symlink to a dir	"linkd"
				    Other symlink	"link"
				On MS-Windows:
				    Normal file		"file"
				    Directory		"dir"
				    Junction		"junction"
				    Symlink to a dir	"linkd"
				    Other symlink	"link"
				    Other reparse point	"reparse"
			user	User name of the entry's owner. (Only on Unix)
		On Unix, if the entry is a symlink, the Dictionary includes
		the information of the target (except the "type" item).
		On MS-Windows, it includes the information of the symlink
		itself because of performance reasons.
