cd boost/filesystem
svn cp ^/trunk/boost/filesystem ^/branches/filesystem_v3/boost/filesystem
svn switch ^/trunk/boost/filesystem
svn rm *.hpp
svn mv v3/*.hpp .
svn rm v2 v3
# modify headers
svn commit -m "Remove Filesystem V2"
svn switch ^/trunk/boost/filesystem
svn merge --reintegrate ^/branches/filesystem_v3/boost/filesystem
svn commit -m "Merge back to trunk"

FWIW, if you're doing this in one go, there's
no good reason to create a branch.
