So Karl: if you write the code to do the client warning when using propset
with values of "off" or "false", maybe make the warning recommend propdel.

   $ svn propset svn:executable false filename
   svn: warning: The value of 'svn:executable' property is ignored by
   Subversion -- the behavior is enabled by the mere existence of the
   property. Your value of "false" looks like one which attempts to
   disable this property's behavior (but will not have that effect).
   If that is what you are trying to do, use 'svn propdel' instead.
