The problem is in url-proxy.el: url-default-find-proxy-for-url returns
"DIRECT", but url-find-proxy-for-url tests for "^direct":

    (cond
     ((string-match "^direct" proxy) nil)

url-find-proxy-for-url binds case-fold-search to t, believing that
this would take care of the case difference, but that is false for
Turkish, because under the Turkish language-environment, we get:

  (downcase ?I) => ?ı

IOW, 'I' downcases into the dotless i.

Does anyone understand why url-proxy insists on using the likes of
"^direct" instead of "^DIRECT", i.e. why it doesn't match the case as
well?
