:HISTORY and :KILLRING to LINEDIT &co can now be pathname
  designators.

  I have no idea what I was thinking when I put the
  META-ESCAPE crap in there.

  Also delete a bunch of trailing whitespace.

  C-S and C-R search history backwards and forwards.

  Also kludgy support for recursive editing.

Also corrected some typos.

* Fixed a bug in completion (when completion was attempted on a fully completed name)
* Default of :if-exists :append to start-debug

Be nicer when updating terminal translations in a live system, put linedit::*debug* in a better place.

 * Fix META-ESCAPE to deal with character literals. Not 100% sure this is the right fix, though, but seems to do the job.

    single character needed to be added.

- Various formedit and repl fixes.

* Added info-string for development time (makes used version and mode visible)
* Nicer interface for DISPLAY
* Robuster smart terminal.
