Below are the diffs for 'sort.c' packaged with version 1.5
If 'sort.c' is used to sort files larger than 20K, it may not
work properly.  Last_line does not reserve a space at the end of
the mem_top buffer for a '\0'.  It fails under the following condition:
the last character in mem_top is a '\n'.  In this case the string
doesn't get terminated correctly since '\0' is appended past the
end of the buffer.
