In the lcd_putc() of common/lcd.c, line 189 handles tab '\t'. And the
following lines:
console_col |= 8;
console_col &= ~7;
seems to have problems. If console_col is 9, it will become 8 after the
above two lines, which means instead of tab of 8 spaces, it goes back
1. Is this intentional or a bug?
I think it should be console_col += 8; instead of console_col |= 8;

A student of probability soon realizes that by its nature the
billion-to-one chance crops up nine times out of ten, and that the
greatest odds boil down to a double-sided statement: it will happen,
or it will not. - Terry Pratchett, _The Dark Side of the Sun_
