other tweaks added by me

help_line_len()
- Make the text display more flexible, and closer to what nano
1.2.x does. (DLR)
- configure.ac:
- Allow more flexible handling of UTF-8 support by allowing
the --enable-utf8 and --disable-utf8 options. (Mike
Frysinger) DLR: Extend these options to work with slang as
well as curses, consolidate the warning and error messages
dealing with UTF-8 support as much as possible, and add a few
minor consistency fixes.
