Not a bug.  A choice made.  But it does seem brain dead to 
restrict the file type.

That means I have to jump through a bunch of hoops to actually be 
able to load a SEQ file.

You want to sometimes.  Because I don't know if we have very 
good file readers.  So might as well load one that way if you want a 
close look at such a file, in the built-in monitor.

Not to mention the fact, we have no 'diff' for the Commodore!  Thus, 
got to pretend to accomplish comparisons manually.
