Just a note:
cmpilato and I discussed the failing blame tests today, and we tracked it down
to svn_fs_contents_changed(). Because the representations are the same,
svn_fs_contents_changed() now returns FALSE, instead of TRUE, in cases where the
two nodes being compared result in a empty delta. This probably impacts more
than just 'blame -g'.

It turns out that svn_fs_contents_changes() is being used to answer multiple
questions, which until now have been answerable in the same way. We'll have to
take a look at whether we fix the existing API, or provide another which allows
us to differentiate these questions.
