ffap and ignoring case in completions

[Ryan Yeske]

;; ignore case in file name completion...
(setq read-file-name-completion-ignore-case t)
;; ...but not other completion
(setq completion-ignore-case nil)

find-file-at-point does not look at the value of
read-file-name-completion-ignore-case, but rather at the value of
completion-ignore-case.  This is inconsistent with the behaviour of
the vanilla find-file function and the documentation of the two
variables.

I believe the patch below solves the problem.
