lynx-dev Keymap printing patch

[Ilya Zakharevich]

I was puzzled why lynx would not print its DOWN_TWO binding.  The
following patch resulted.  Note that

  a) This patch does not help with bindings keys which are not visible
        in the current font: try binding 0x81, this will result in some
        invisible entry (is not this a bug in the display code?);
  b) This prints some unexpected funny bindings, like

0x1b8       ABORT         quit the browser unconditionally
0x1cb       ACTIVATE      go to the document given by the current link
0x1cf       IMAGE_TOGGLE  toggle handling of all images as links
0x1d0       PREV_PAGE     view the previous page of the document
0x1d1       NEXT_PAGE     view the next page of the document

Do not know why.  (But the code printing this is important to debug
assignments similar to KEYMAP:0x210:LEFT_LINK.)

Enjoy,
Ilya
