And that is a problem?  This use case is explicitly for human use (in contrast
to the +LINE:COLUMN FILE case which is for programs that call $EDITOR).  And it
is a rare use case on top of that.  So why typing a few words is a problem, and
why does it justify yet another tweak of the UI?

But if we do want to make this easier, I'd go with a new command-line switch,
say, "--eob".  The Vim way is cryptic and error-prone, so I don't think we
should do the same.  And I don't see at all why would someone needs to say "N
lines from EOF".
