Hello,

After lexical-binding was enabled in ediff, doing ediff-files gives this
error:

Debugger entered--Lisp error: (void-variable file-A)
  ediff-find-file(file-A buf-A ediff-last-dir-A startup-hooks)
  ediff-files-internal("~/temp/d" "~/temp/a" nil nil ediff-files)
  ediff-files("~/temp/d" "~/temp/a")
  eval((ediff-files "~/temp/d" "~/temp/a") t)
  eval-expression((ediff-files "~/temp/d" "~/temp/a") nil nil 127)
  funcall-interactively(eval-expression (ediff-files "~/temp/d" "~/temp/a")
nil nil 127)
  call-interactively(eval-expression nil nil)
  command-execute(eval-expression)

Recipe:

Take any 2 files and do M-: (ediff-files "file1" "file2")
