New Revision: 212235
URL: http://svn.freebsd.org/changeset/base/212235

Log:
  libedit: Try to map <Delete> to ed-delete-next-char.
  
  This adds a new "arrow" key "delete" corresponding to the kD termcap value.
  It only works if that is a sequence such as "\033[3~"; if it is "\177", the
  em-delete-prev-char or ed-delete-prev-char from the single-character
  mappings remains. It turns out that most terminals (xterm and alikes,
  syscons in xterm mode) produce "\033[3~" by default so <Delete> has the
  expected effect.
  
  This also means that things need to be considerably misconfigured for
  <Backspace> to perform a <Delete> action.
