This patch fixes two bugs in finder-exit:

- It treats buffer *Finder-package* also.
  This buffer is used by `finder-commentary'.

- Instead trying to avoid `delete-window' for
  `one-window-p', it wraps it in `condition-case'.

Here is an updated finder.el patch, which includes the bug fixes mentioned
previously. This patch adds two minor features:

* It uses a new syntax table, which inherits from
emacs-lisp-mode-syntax-table.  It does not consider `;' to be comment syntax
(so you don't get highlighting of half of a Commentary sentence that
contains `;').

* It font-lock highlights text between quotes: `...', as in Emacs-Lisp doc
strings.

Without these enhancements, finder uses Emacs-Lisp mode syntax, but with the
`;;' line prefix removed, which doesn't make much sense. With these changes,
a Commentary becomes quite readable.

Actually, it does not inherit because it uses `copy-syntax-table'.
Please use `make-syntax-table' so it indeed inherits.

font-lock-add-keywords is best avoided in general.  Please set
font-lock-defaults properly instead.

Done. I guess just substituting make-syntax-table for copy-syntax-table is
sufficient.

New patch attached.

This just sets to use either one of (finder-font-lock-keywords
lisp-font-lock-keywords lisp-font-lock-keywords-1
lisp-font-lock-keywords-2) depending on font-lock-maximum-decoration.
Based on the comment in finder-font-lock-keywords, it doesn't seem to be
the intention.

On a similar note, I'm not sure why we should use the font-lock rules
from lisp-mode, since the buffer's content won't be Lisp code.

The idea was that a Lisp library Commentary sometimes refers to Lisp keywords,
sexps, and so on. But I agree.

New patch attached.

Looks good.  Can you provide a ChangeLog entry?
