Normally, The users in East Asian will setting to Unicode East Asian Ambiguous characters are wide.

A example, Terminal on Mac OS X:
Terminal.app's Preferences menu > Settings > Advanced tab > Check the Unicode East Asian Ambiguous characters are wide

Unicode East Asian Ambiguous characters are wide means displayed a UEAA character consuming the area of ​​_2_ characters. It's critical issue when writing letters in Japanese and other languages.

see also: http://www.unicode.org/reports/tr11/

So, A problem of bpython is using u'\u2500' character when displaying the auto-completion list, because u'\u2500' character is UEAA character.

It should use - (hyphen) or any non-UEAA characters instead of UEAA characters.

Thank you.
