I tend to agree: in general, allowing the vacuous case tends to be
useful.  Johan's example of hanging a non-empty log message on
a revision that lacks a non-empty text-delta is a perfect example of

Another example is creating padding revisions.  When we migrated to ASF,
we had to incur a revision numbers offset of 840074.  It would have been
reasonable to create 26 padding revisions to make the offset a round
number.  Those revisions wouldn't have needed any content.  If
Subversion forbade revisions with no changed-paths, we would have had to
create dummy changes — but, at that point, we would be working around
a limitation of the tool.
