Patch: fixlets to dwarf-mode.el

[Tom Tromey]

This patch fixes a few minor issues in dwarf-mode.el.

First, it adds a trailing comment.  This lets you install the file using
package.el, e.g., M-x package-install-file.

Next, it fixes a byte compilation warning found when doing this.

Finally, it bumps the version number, which I think is a nice thing to
do whenever modifying it.  In most cases this is needed so that
package.el will install the updated version; in this particular case
that could be avoided (since one cannot install the unpatched version),
but I felt it was a good practice to get into.

Ok?
