2953	floating point exception with editor_tab_spacing=1	Enlik	andrew_b	"editor_tab_spacing=1 in mc.ini and executing something like:
mcedit filename

leads to SIGFPE.

The problem seems to be here (disclaimer: quick look):
./src/editor/edit.c:3261
this part: 
edit->curs_col % (HALF_TAB_SIZE * space_width)

HALF_TAB_SIZE is defined as ((int) option_tab_spacing / 2), so when option_tab_spacing is 1, it leads to num % 0.
