UTF-8 fix for Shift+Enter

[Koblinger Egmont <egmont uhulinux hu>]

Hi,

With the UTF-8 patches, line editing (both the command line as well as other
widgets: create dir, rename file...) go crazy if a literal newline
(Shift+Enter, or Ctrl+Q followed by an Enter) is pressed. This special
character can no longer be removed from the buffer, the cursor walks to the
left and so on...

I created a patch called 00-82-utf8-shift-enter.patch, it is available
either from this bug entry:
  http://savannah.gnu.org/bugs/?func=detailitem&item_id=17268
or from the usual place of our mc patches:
  https://svn.uhulinux.hu/packages/dev/mc/patches/

The savannah bug entry as well as the comments on the top of the patch file
explain the bug and its solution in more details.


bye,
Egmont
