Problem: libedit is a very pure-ASCII oriented library, and it is not aware of extended (0x80..0xFF) or even multi-byte characters. It considered such characters as non-printable and didn't allow to input them. Fix: make libedit think that all bytes >= 0x80 are printable. cmd-line-utils/libedit/el.h: Defining macro, a locale's isprint() replacement. We'll consider all 8bit values as printable characters. cmd-line-utils/libedit/key.c: Changing isprint() to el_isprint(). cmd-line-utils/libedit/map.c: Changing isprint() to el_isprint(). cmd-line-utils/libedit/read.c: Changing isprint() to el_isprint(). cmd-line-utils/libedit/refresh.c: Changing isprint() to el_isprint().
