The prepare-ChangeLog script uses 'svn diff' instead of 'svn stat' to get a list of changed files for a ChangeLog entry. The 'svn diff' command skips moved/copied files unless they've been changed after they were moved. The best way to fix this is to switch to using 'svn stat'.
I think we had been using svn diff because svn stat was orders of magnitude slower. Not sure if that improved with the new svn, though.

Yes, I made that change in r14814 (Bug 9395). However, r15025 (Bug 9570) let you specify a list of files and directories to operate on, which will greatly improve speed when running and helps if you're working on multiple patches in the same working copy.
