Re: creating empty file

Hello Mirko,

Surely that's true and desirable. In the last consequence this means
that you could reliably detect when a sequence of modifications results
in the same state of the buffer as the state at the time the buffer was
loaded, so that the buffer should be marked unmodified.

I think this is a possible, but time-consuming task. One could think
about computing a hash about the buffer contents at every modification,
but this would take a lot of time at all.

Best regards,
