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

  Default highlight color should be NIL.

  Sanity!

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

  Also kludgy support for recursive editing.

Modern versions of Osicat provide calls equivalent to signals.c, so we
can get rid of some UFFI cruft in preparation for migration to CFFI.
Also, /lib/terminfo/ added to *terminfo-directories* for modern Debian
systems.

* <blush>Type Julian's name correctly</blush>

* Copyright updates: add 2004 and Julian.
* Make the dependency on Osicat 0.4.0 explicit. Yuk.
  Asdf/asdf-install should grow version management...

Improved quoted string detection a little.
 * Added basic sexp-motion commands.

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

 * Even better filename completion.

* New Terminfo license. (Yay!)

* Other stuff.

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

- Refactored internals.
