version.c: update NA

7.4.797:

- Modified function redraw_asap was removed in
  e0e41b30c6,
  together with its only caller check_termcode.
- Grepping for the following regexps did not yield any result in
  nvim/src and its subdirectories: rows.*\*.*Columns (lines modified
  often), ScreenLinesC\[r\] (one of the sources of the bug),
  msg_scrolled followed by grepping for NORMAL (another line that was
  changed for the bug)
- The out-of-bound access was on the array *screenlineC[MAX_MCO] (see
  the diff). I grepped for MAX_MCO an checked every array of that length
  for out-of-bounds access in its scope (I did not check for called
  functions, e.g. utfc_ptr2char(p, u8cc) where u8cc was of length
  MAX_MCO). I did not find any.
- The code for drawing on the screen was moved to the TUI, which was
  newly written.

7.4.733:

- test_listchars was converted to a lua test in
  https://github.com/neovim/neovim/pull/2492
- Since no file is sourced anymore, the behavior of the lua test should
  not depend on the setting of ff
