Funny.  That was me having problems with filtering out directories
as well :-)  I thought your patch was added using the --prune-empty
flag.  I guess you can comment on that.  I can confirm that I've got
nice and clean filtering using

  * git filter-branch --subdirectory-filter <dir> --prune-empty
--tag-name-filter cat -- --all
  
followed by the steps above.  I use qgit with the tree-view enabled
to find the place where the hierarchy changes from the complete one
to the only-this-dir one.  You can do a binary search for that and
you spot the exact commit easily by the gap in the history-line.  Then
I run this little bit of code:

#!/bin/bash

contains="$1"

git tag | sort > tags.all
git tag -l --contains $contains | sort > tags.keep

for t in `comm -23 tags.all tags.keep`; do
  git tag -d $t
done

Not ideal, but doable.

	Cheers --- Jan
