"svn log --xml" is modified by both "-v" and "-q". I wondered whether it is
appropriate to do so, and decided that there was no harm in "svn ... -xml"
having such variants that match the non-XML mode; it is no problem for a script
to provide the options to give the data that it wants.

On the other hand, in "svn log", both "-v" and "-q" control the addition of
potentially quite large amounts of data, and this could be considered a valid
reason for the options. This is not the case with "svn blame -v" or "svn info
-v", and so I tend to agree that it is more appropriate to just output all the
fields anyway. Anyone else?
