Yes.  I guess that's why I employed filter-branch to begin with.

Okay, I misread your command line.  For some reason I thought "-f" was an 
option to add.

*giggle*  I'm not quite sure what makes this funny to me, but it made me 
laugh.

You are right; that's not what I want.  But, it is a good second-place 
result that I'll keep in mind.  Sometimes keeping the history at all is 
more important that keeping the history orderly.

Again, thanks for the help.
