*Others and* Unix porters: do you recognize this one?

I made a posting last week, about troubles finding the
image and changes file, right after doing a 'save as'
on a Unix platform.

There is actually a small fix for this, which applies to 
all platforms.

Revise the SystemDictionary>>saveAs method, to pass the complete file
pathname to the method SystemDictionary>>imageName:

The change causes the method FileDirectory>>default to maintain its
correct value following a 'saveAs'.

I have tried this on a Mac, W95 and Unix image, but the usual
cautions apply.

Andreas provided a good clue; as usual, spelunking in the browser
was very easy.
