Thanks, but that would generate duplicates in the ChangeLog files.  For example, 
if a patch updates both lisp/Makefile.in and src/Makefile.in, it would copy the 
patch's change log entry to both lisp/ChangeLog and src/ChangeLog.  Plus, it's 
not clear how to generate the "leftover" ChangeLog at the top level, which 
contains everything not in the subsidiary ChangeLogs.
