On minibuffer completion (Cygwin)

[Angelo Graziosi <angelo.graziosi@alice.it>]

Since these changes:

* minibuffer.el (read-file-name-completion-ignore-case):
   Add cygwin to the list.

often I need to type two keys to complete a name, while before it was 
sufficient only one key.

For example, if I have

foo
Fio

then before: 'f<TAB>' worked fine and the completion was 'foo'; 'F<TAB>' 
==> 'Fio'. Now I need 'fo<TAB>' or 'Fi<TAB>'.

Usually Cygwin is strictly case sensitive by default, even if it 'lives' 
on a OS case insensitive. For ex.: 'mv emacs.mail Emacs.mail' works; 
only 'cp emacs.mail Emacs.mail' doesn't.

So, why Emacs can't do what Cygwin can at its prompt?

To be short: my opinion is that Cygwin shouldn't be added to that list!


Cheers,
    Angelo.
