Bug#669319: bhl: visiting .bhl after --remove

Package: bhl
Version: 1.7.3-2
Severity: normal
File: /etc/emacs/site-start.d/50bhl.el


    dpkg --remove bhl

visiting a .bhl file

    emacs23 -q /tmp/foo.bhl

gives an error

    File mode specification error: (file-error "Cannot open load file" "bhl")

where I hoped it would just give fundamental-mode or whatever.

dpkg --remove leaves behind conf files like 50bhl.el.  Generally the
lisp startup should check for the package contents before making an
auto-mode-alist setup.  Eg.

(if (not (file-exists-p "/usr/share/emacs/site-lisp/bhl.el"))
    (message "bhl removed but not purged, skipping setup")

  (autoload ...)
  (add-to-list '...))

Incidentally, the auto-load-alist regexp usually should be


rather than "\\.bhl$" since $ matches a newline whereas \\' is end of
string -- in the highly unlikely event a non-bhl file has ".bhl\n" in
its name :-).
