What I most like about Dave's change is the improved separation of
concerns:  it allows the OS to invoke an image with the proper startup
script and/or arguments WITHOUT relying on Preferences
readDocumentAtStartup being set correctly.  I can see -filein being useful
for a production patch use-case, but the rest of those go back to mixing
the Smalltalk environment in with the operating-system environment.  For
safe and scalable headless interaction, you would just use a server.  I
never knew if there was an actual use-case for -evaluate and -cli other
than novelty.  Is there?
