lynx-dev SUPPORT_MULTIBYTE_EDIT

[Hataguchi Takeshi]

I wrote a patch concerned with SUPPORT_MULTIBYTE_EDIT referring
Klaus's comment (*). The routine which is enabled by
SUPPORT_MULTIBYTE_EDIT provides better support of CJK characters to
Lynx's Line Editor.

(*) http://www.flora.org/lynx-dev/html/month121999/msg00295.html

This patch defines SUPPORT_MULTIBYTE_EDIT. I belive there are no side
effects.
