  Enabling arrow keys requires some work.  You should call some function
(I don't remember its name, something like termios_enable_arrow_keys) in
your program.  Compiling standalone readline from bash is not easy.  It is
better to compile it together with bash, then it defines USE_BASH? and
some things are different from standalone version.  I wonder if standalone
GNU readline will understand arrow keys, if termios_enable_arrow_keys
is used (this function is in bash sources somewhere?).

  And when editing long line, readline from bash scrolls one line
instead of wrapping to the next.  This is annoying, when you have to scroll
back and forth to see what you have typed already.

  I have a project which uses readline from bash, if you are interested
to see how it is used, I can send it by mail or place on WWW.

BTW, I don't remember exactly, but I think GNU readline can be compiled
with DJGPP (maybe together with termios lib from bash).
