view: /$INBOX/: show "messages from $old to $new"

With the ViewVCS commit view using /$INBOX/?t=YYYYMMDDhhmmss-
links, the use of `t=' may not be immediately obvious to a
reader and confuse them into thinking the inbox hasn't been
updated in a while.

So add a header to the top of the page whenever the `t=' query
parameter is used.

And kill a couple of redundant variable assignments while we're
at it.
