Add `file-system-ignore-case-p', use it. 2009-10-24 Aidan Kehoe <kehoea@parhasard.net> * files.el (default-file-system-ignore-case): New variable. (file-system-case-alist): New variable. (file-system-ignore-case-p): New function; return t if file names under PATH should be treated case-insensitively. * minibuf.el (read-file-name-1, read-file-name-internal-1) (read-file-name-internal-1): * package-admin.el (package-admin-check-manifest): Use file-system-ignore-case-p instead of checking system-type directly in these functions. (Even though minibuf.el is dumped before files.el, the function is only called in interactive usage, there's no dump time order dependency here.)
