Known problems
--------------

This version of bash/readline supports multi byte handling
that is e.g. wide character support for UTF-8.  This causes
problems in geting the current cursor position within the
readline runtime library:

bash-4.2> LANG=ja_JP
bash-4.2> echo -n "Hello"
bash-4.2>

In other words the prompt overwrites the output of the
echo comand.  The boolean variable byte-oriented
set in /etc/inputrc or $HOME/.inputrc avoids this
but disables multi byte handling.
