I compared with how completion works for C-x d. In this case the default 
directory is used when the string is empty. This is of course not 
meaningful the the custom widget.

I noticed another problem (bug?). The completion list contains all 
files, not only directories. This is meaningful for C-x d, but not for a 
directory widget. To summarize the problems:

1) On w32: You can not get completion when the widget input field for a 
'directory type custom is empty. This perhaps has something to do with 
the absence of a definition of a root directory in dired too?

2) Completion for a 'directory type custom widget includes all files, 
not only directories. (Is this w32 specific?)

3) Alt-Tab is useless as a default since it is not available in window 
type environments. Esc-Tab is in this case available, but is not always 
the case. (This message has been repeated many times now and I really 
long for a resulotion of this.)
