CAVEAT: Not a developer, but someone interested in keywords in general.

Personally I think it would be _much_ more surprising to automatically 
unexpand the keyword when the matching property is deleted.  If someone 
sets one of the expanding properties and the unsets it, either they made 
a mistake in the first place (and should revert that expanded text on 
their own) or they meant to do that to freeze the expanded text (and 
hence the diff is completely legit).

For example, a site policy is that all new files are to be created with 
svn:keywords "Author" set and then committed.  Then, the svn:keywords 
"Author" is to be removed and the file committed again, thus orphaning 
the original Author information in the file for all time.  Sure this is 
stupid, but it does correspond to some behavior that has been used in 
CVS in the past (although there I believe it was freezing $Id$ on tags).

My 2 cents
