-;; BUG REPORTS

-;; Please send bug reports to me at ericding@mit.edu.
-
;; Known bugs/features:
;; * goto-address-mail-regexp only catches foo@bar.org style addressing,
;; not stuff like X.400 addresses, etc.
;; * regexp also catches Message-Id line, since it is in the format of
;; an Internet e-mail address (like Compuserve addresses)
-;; * If show buffer is fontified after goto-address-fontify is run
-;; (say, using font-lock-fontify-buffer), then font-lock face will
+;; * If the buffer is fontified after goto-address-fontify is run
+;; (say, using font-lock-fontify-buffer), then font-lock faces will
;; override goto-address faces.
