Looks like a reasonable approach.  Be careful with errors from :eval
expressions, e.g.

  (:eval (abbreviate-file-name (buffer-file-name)) )

will give you annoying error messages when redisplay is performed when
(buffer-file-name) yields nil.  Of course you can ensure that show-path
is always nil in this case ... but

    (:eval (and buffer-file-name (abbreviate-file-name buffer-file-name)))

is probably safer.


Michael.
