patch 9.1.0218: Unnecessary multiplications in backspace code
Problem: Unnecessary multiplications in backspace code, as
"col / ts * ts" is the same as "col - col % ts".
Solution: Change "col / ts * ts" to "col - col % ts". Adjust the loop
and the comments ins_bs() to be easier to understand. Update
tests to reset 'smarttab' properly.
