23.1; rfcview.el: please add buffer-local rfcview-title variable

[trentbuck]

I would like to customize frame-title-format such that when I'm
looking at an RFC with rfcview.el, I can set the frame title to the
RFC's title.  For example, when looking at rfc3481.txt I want

    "TCP over Second (2.5G) and Third (3G) Generation Wireless Networks"

AFAICT rfcview.el currently provides no such variable, but it DOES
recognize the title line (lines?), so I think it would be relatively
easy to set a buffer-local rfcview-title variable when rfcview-mode is
activated by leveraging title-line-point in rfc-grok-buffer.
