Subject: MEDIUM: tools: read_line_to_trash() handle empty files without \n

MEDIUM: tools: read_line_to_trash() handle empty files without \n

fgets() returns NULL when EOF is reached before newline, handle
that as a success for consistency, current behaviour is arguably a bug,
the API of fgets() is pretty weird after all so someone probably forgot.
