patch 9.1.0399: block_editing errors out when using delv9.1.0399
Problem: block_editing errors out when using del
(@Jamarley)
Solution: Change ins_len from size_t to int and
properly check that it doesn't become negative
There is a check in os.c that verifies that `ins_len` does not become
negative:
```
if (pre_textlen >= 0 && (ins_len = len - pre_textlen - offset) > 0)
```
However this only works, if ins_len can actually become negative and
unfortunately, ins_len has been declared as `size_t` so instead of
becoming negative it will wrap around and be very large.
So let's define it as integer, after which the condition above
properly catches this condition.
