> Anyway, it's the prepare_to_modify_buffer in call_process what does it.

Actually, I think the problem is that the code there calls
decode_coding_c_string even if we read zero bytes from the process.
With some coding-systems, this will insert something into the buffer,
so the call to prepare_to_modify_buffer is justified.

But I agree that the previous behavior was sweeping a subtle bug under
the carpet.
