SVN has two types of externals (both set via svn:externals properties on
directories).
Regular externals (supported for a very long time) pull in external SVN
trees inside your checkout. Because they get their own .svn root, vc-svn
handles these just fine.
File externals (added more recently; in 1.7 I think) allow you to pull in a
single file from elsewhere in your repository; sort of the SVN equivalent
of a hard link.
It is these files that vc-svn does not recognize as svn-controlled right
now.

Well it makes vc-svn recognize the files as svn-controlled, so it
definitely works better :-)
I'll see about putting a fixed version in a private load path, so that if
it breaks something it doesn't affect all users.
