: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.

 Use :IF-COMPOENNT-DEP-FAILS :TRY-NEXT in .asd for better system
 introspection.

 Add a "generic" port which only signals an error for INSTALL-REPL
 and UNINSTALL-REPL.

Also corrected some typos.

 * Don't intern read symbols before passing them to the system.
 * Better directory completion (via Osicat).
 * Fixed AGAIN: editor confusion after completion.

- Various formedit and repl fixes.

* New Terminfo license. (Yay!)

* Other stuff.

- Refactored internals.
