Finn Thain 6ce95df245 m68k: Fix lost column on framebuffer debug console ... commit 210a1ce8ed upstream. Move the cursor position rightward after rendering the character, not before. This avoids complications that arise when the recursive console_putc call has to wrap the line and/or scroll the display. This also fixes the linewrap bug that crops off the rightmost column. When the cursor is at the bottom of the display, a linefeed will not move the cursor position further downward. Instead, the display scrolls upward. Avoid the repeated add/subtract sequence by way of a single subtraction at the initialization of console_struct_num_rows.
