I wasn't saying the file should be deleted and recreated. I was saying
that the file in the destination should be deleted in a revision
before the file is moved to that destination. So that git will
understand that they are different files. i.e.

svn rm boost/filesystem/path.hpp
svn commit
svn mv boost/filesystem/v3/path.hpp boost/filesystem/path.hpp
svn commit

(although obviously not doing a single file at a time)

We're not talking about tacking branches. We're talking about
retaining the history of a moved file. Did you look at the examples I
posted? They illustrate the issue.
