Are you refering to this code?
#define matrix (*matrix)
#define map (*map)
char map[an + 1][bn + 1] = emalloc(sizeof(char[an + 1][bn + 1]));
size_t matrix[2][bn + 1] = ecalloc(1, sizeof(size_t[2][bn + 1]));
Perhaps the #define:s makes it confusing, but I though the code
beneath it should be simplified by them and that it was worth it.
I was suggested to use
size_t (*matrix)[n][m] to simplify the matrix allocation.
Remove the #define:s and write (*) explicitly?

Are you refering to the this code?
sprintf(buf + (sizeof("0000-00-00 00:00:00.") - 1), "%09lu", attr->st_mtim.tv_nsec);
There are no checks, and the buffer is guaranteed
to be large enough, so I disagree about using snprintf.

I will look into these.

Does it matter if stdout is a TTY? Anyway I rather remove
it than add another flag. But lets see what everyone thinks.

stdin (via -) should be supported.
