On minibuffer completion (Cygwin)

On minibuffer completion (Cygwin)

[Angelo Graziosi]

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.

Eli, you originally suggested adding cygwin to the list.  What's your
opinion about this?

My opinion is that Cygwin runs on a case-insensitive filesystem, and
therefore should behave accordingly.  Users who don't like that can
always customize Emacs.

But if the Cygwin system itself (i.e. the Cygwin utilities) tries to
pretend that it runs on a case-sensitive filesystem, then Emacs should
follow that convention.
Where's the maintainer of the Cygwin port?
