PATCH: accept-line-and-down-history

You've already seen this since it was accidentally wrapped up in the
$CUTBUFFER/$killring patch, but it's completely separate and I won't
commit it with that.

This changes the behaviour of accept-line-and-down-history to accept the
line unconditionally, even if it can't go down in the history.
Previously, if you were on the last line in the history it just beeped.
The thinking behind this is that you can use this as a replacement
binding for accept-line, getting the down-history behaviour for free
when you're not at a newly typed line.  However, you have to remember to
type `\e>' when you're finished with the previous history chunk or you
keep getting new lines.  Even so, can anyone suggest a reason why the
old behaviour would be a feature?
