Fix out of bounds memory access (off by one)
If fgets reads a line that only contains a `\n`, then the pointer `eol` will point to the first byte in that buffer. The subsequent dereference of `*(eol -1 )` will access the byte before that buffer. This fix makes sure that that length of the current line read by fgets is at least 2 bytes long.
