The change is experimental rather than final.  I've documented it in  
NEWS for now.

With the introduction of `read-file-name-completion-ignore-case'  
there's less need to have an MS-Windows specific
default value of `completion-ignore-case'.  However, buffer names --  
particularly those that are based upon filenames -- would probably  
benefit from case-insensitivity in completion, at least on systems  
with case insensitive file systems.  Are there any other examples  
where case sensitivity is problematic?
