Review `bind' tree resolving..

Review `bind' tree resolving..

So with this change, adding onto
  [b726bcaec04e062198cc4ffee03aa0039709bed5],
  [350e4be5b9fa4b4a0c100c10eb2e11166082ae13],
and especially
  [3c52d1697aa5365f4edb6febf90222fef97be839],
should our `bind' tree be capable to deal with inter-key-timeouts.
In fact the old code has never been reviewed as such, i stopped
once it seem to work enough to make me happy.  Never had a MLE
review, too, the necessary line-redraw optimization is still
missing.  Truth is, it was a piece of shit, when i looked at it.
