If we did that, then people would complain "I'm using 2.16.2 but
convert-ly only updates my file to 2.16.0!".  This could be
avoided by printing a message to the effect of "no changes to
apply; not changing version number in the file".

As a general rule, I don't think it matters whether we make -d or
not -d the default; what matters most is providing good
information to the user in some combination of program output
and/or documentation.
