I've rechecked this, and my assumption that it was linebreaks was incorrect - 
instead its that non printing characters are converted to periods (.).
To test this, save a stream to a file (using the ASCII option), and compare 
the output of "od -t xz stream_save_file" with the hex dump in the dialog.

It's necessary to save the stream as formatted if you want to be able to save 
a hex dump, so I don't think this is a bug - although personally I would 
prefer the save button ignored the formatting selected, so I could generate 
the hex dump from the raw data file.

The extra radio button sounds like a good idea... and funnily enough, I reckon 
it would be the easy enough for yours truly to implement.  Hopefully the text 
widget we're using can take that sort of punishment (raw binary data).  I'll 
get working on a patch then, unless people think that the behaviour of the 
"Save As" button should be changed.
