[patch ready] mcedit puts cursor in the middle of multibyte utf8 character

Reporter	sergem

Sometimes when editing an UTF-8 file mcedit puts cursor in the middle of the multibyte utf8 character. And when it does, typing a new character results in an invalid utf8 sequence.

I've made some general purpose utf8test file and attached it. To reproduce this bug:

1. Open this file in mcedit
2. Put cursor to the end of "Combination of 2bchar + incorrect chars" line
3. Press "Left" 5 times (notice, cursor moves 2 characters at a time)
4. Press "q"

And you'd get a broken character.

PS: This bug is related to #2372 and #1730 but different from them.
