Case-Insensitive Sorting in Dired on OS X

I like my dired directory listings to be sorted by name regardless of case. This was a bit fiddly to get working in OS X, but I found a solution using the built-in ls-lisp with a few extra options, rather than the system ls to generate the dired listing.

Here are the required settings:

;; using ls-lisp with these settings gives case-insensitve
;; sorting on OS X
(require 'ls-lisp)
(setq dired-listing-switches "-alhG")
(setq ls-lisp-use-insert-directory-program nil)
(setq ls-lisp-ignore-case t)
(setq ls-lisp-use-string-collate nil)
;; customise the appearance of the listing
(setq ls-lisp-verbosity '(links uid))
(setq ls-lisp-format-time-list '("%b %e %H:%M" "%b %e  %Y"))
(setq ls-lisp-use-localized-time-format t)

One downside of this is that it breaks dired-quick-sort, but I can live with that.
