When you moved the repositories to Subversion, that was the perfect
opportunity to move away from legacy stuff as well...

In the long run, I think this is not a practical solution.

It is not true that the hooks can't identify the files committed to the
repo. The hooks are provided with two arguments, the repository path and the
revision number. You can use these two with the 'svnlook' or 'svn' commands
and get almost any information (including the filenames, with full path,
that changed for that revision) that you want.
