usr.bin/col : col.c
Log message:
1) Fix a segfault triggered by an input line containing two consecutive
backspace characters beyond column MAX_SHRT, overflowing c_column.
2) Fix imcomplete initialization of the final element of the *count
array by adding a missing pair of parentheses.
3) For code clarity and extra safety, change all variables dealing
with column numbers from int to size_t such that they cannot overflow.
Found while reviewing the patch from deraadt@'s reallocarray() rampage.
Feedback and OK millert@.
