flymake info file has wrong command name (flymake-build-relative-path)

[asc]

Looks like this might change anyway (based on fixme comment in lisp), but for
this cut-and-paste elisp writer this tripped me up.

File: flymake,  Node: Example -- Configuring a tool called directly,  Next:
Example -- Configuring a tool called via make,  Up: Adding support for a new
syntax check tool

Example - Configuring a tool called directly
--------------------------------------------

   In this example, we will add support for `perl' as a syntax check
tool. `perl' supports the `-c' option which does syntax checking.

   First, we write the `init-function':

     (defun flymake-perl-init (buffer)
       (let* ((temp-file (flymake-init-create-temp-buffer-copy
                          buffer 'flymake-create-temp-inplace))
              (local-file  (concat (flymake-build-relative-path
                                                           ^^^^
---------------------------------------------------------------------------

(defun flymake-build-relative-filename (from-dir to-dir)
                              ^^^^^^^^
  "Return rel: FROM-DIR/rel == TO-DIR."
  ;; FIXME: Why not use `file-relative-name'?
