No problem, I can add this.

You you really need to get the plaintext;  --verify does not emit the
text and I am not sure whether I can easily add it to the 1.0 series
without breaking too much.

Hmm, as said above - seems to be a too large change for 1.0

If you mean the size of the file, this is no problem:  The size of the 
signed text needs much more code at different places.

Okay, I'll emit a start and done marker (the done marker may be
helpful when we later enhance this system).

So for each file you will see on status-fd this:

    FILE_START <what> <filename>
	Start processing a file <filename>.  <what> indicates the performed
	operation:
	    1 - verify

    FILE_DONE
	Marks the end of a file processing which has been started
	by FILE_START.

If this is helpful for you, I'll code it and post a diff.
