Re: Bug in dir() leads to Unicode and win_dir()

Hi Greg

My Bad.  It seems win_dir("F:\\DATA\\MUSIC") literally means "give me the
directory entry "MUSIC" in F:\DATA

I guess the confusion on my part is that the standard Euphoria dir() was
giving me F:\DATA\MUSIC\* without me adding a trailing slash to the pathname.

This must be the operating system's default behaviour as dir() just calls
a machine function, like typing in DOS, "dir F:\data\music" will show the
contents of the music folder, not

07/06/2005  12:08 PM    <DIR>          music
               0 File(s)              0 bytes

Now when I do win_dir(pathname & "\\") it works, however replacing dir()
with win_dir() in walk_dir() doesn't recurse properly.

Do you think it's worth trying to find the cause of this and fix it in
win_dir() or to implement a new walk_win_dir() ?

IMHO, the standard Euphoria (/DOS) behaviour is nice, because if you want
the folder attributes for the folder you are looking at you need only 
examine the '.' entry?

Good job on this BTW :)
