Bug in ls.c

Hello there.

I don't know if anyone has reported this yet, but
if not, ls.c in the GNU fileutils package (v4.1 and
all older versions) has a bug on line 2534.

The line, reading:
    "output_block_size < 0 ? output_block_size : 1));"

Should almost certainly read:
    "output_block_size < 0 ? 1 : output_block_size));"
    
This fixes the use of the "-k" option (among other things)
when listing files using the "-l" format.
