Enrico asked:

        I left out one possibly important piece of information: My initial 'git svn fetch' used '-r' to "cauterize" the history, both because there is a lot of it (almost 12 years) and because the repository was reorganized significantly after a cvs -> svn migration.  The first revision I have is r83875:

$ git log --max-parents=0 --all --date-order | tail -n 1
    git-svn-id: svn://dev.carnegielearning.com/trunk@83875 752fcc94-cd22-0410-baa8-ef54ac2c6973

        So to answer Enrico's question: Prior to the initial revision that was fetched into git, these files did live in a different top-level directory.  However it's not one that's matched by the 'ignore-paths' regex.  Here's one example:

$ svn log -v svn://dev/branches/localization-merge/buildprocess/antfiles/dmg.xml | grep /dmg.xml | uniq -c
      9    M /branches/localization-merge/buildprocess/antfiles/dmg.xml
     35    M /trunk/buildprocess/antfiles/dmg.xml
      1    A /trunk/buildprocess/antfiles/dmg.xml (from /trunk/buildprocess/assemble-support/dmg.xml:48305)
      1    D /trunk/buildprocess/assemble-support/dmg.xml
     57    M /trunk/assemble-support/dmg.xml
      1    A /trunk/assemble-support/dmg.xml

Here are the svn revisions that explain the transition from 'assemble-support' to 'buildprocess/assemble-support', just after the cvs -> svn migration.
