I'm not a fan of this. The working copy root can be either above or
below the usual/customary level for creating the tag: when rolling a
Subversion release my wcroot may be ^/subversion,
^/subversion/branches/1.11.x, or
^/subversion/branches/1.11.x/tools/dist. Ultimately, it's a random
environmental value, like ~/.subversion/config settings. Any workflow
that diffs these files using anything other 'svn diff' — for example, diff(1)
or rsync — is going to run into the differences. (For example, our release

There were discussions of this back in 2011/2012, for example, about
recursing upwards to the nearest path-wise ancestor that has an
svn:branchroot=yes property set, or the nearest path-wise ancestor that
is a copyfrom-wise descendant of trunk (i.e., has the same node-id as
trunk's noderev). [1] This has the advantage that the keyword will be
expanded in the same way in all working copies, and even in
mod_dav_svn [2].
