Hi -

I just posted the code condensing sources in 4.1. It looks like it works 
fine; if anyone wants to try it (in a throwaway image please!) run it via:

	Smalltalk appendChangesTo: 'mytest.sources'.

This will copy the old sources, append the condensed changes and run the 
image with the new sources file. Everything should continue to work as 
is, but method histories should show both, the latest 4.1 version and 
the original 4.0 version (but not the intermediates).
