It sure would, but wouldn't this mean we'd always create a buffer and  
copy the string? I'd rather not lose the ability to use the indexing  
into the input
buffer. Just recording the indices and copy to buffer once I see a  
bang and pick up after that was the first idea I had...
I could probably set some flag if I've seen a bang and only then  
really copy the buffer. Yeah, that might work...
