less: correctly account for tabs when rewrapping lines
Lines are rewrapped when the terminal width changes or line numbers
are enabled/disabled. The current calculation always adds eight to
the line length for a tab whereas it should only add enough to move
to the next tab stop.
This doesn't affect the display of lines, which is handled elsewhere
and gets tab stops right, but it does cause lines to be wrapped at
the wrong position.
