svndumpfilter has bug?

["J.K.Lee" <ei...@hanmisemi.com>]

I cannot exclude just only 'db' folder from my repository.

folders and files in my repository are like this:

   trunk/myproj/db/
   trunk/myproj/db/blar.db
   trunk/myproj/dbaccess.cpp
   trunk/myproj/something.cpp
   branches/mynewproj/db/
   branches/mynewproj/db/blar.db
   branches/mynewproj/dbaccess.cpp
   branches/mynewproj/something.cpp

i made branch from trunk/myproj to branches/mynewproj
and modified mynewproj/dbaccess.cpp

now, i want to permanently delete branches/mynewproj/db/*, 
so i executed command like this:

  svnadmin dump myrepos | svndumpfilter exclude branches/mynewproj/db/ | svnadmin load filteredrepos

but branches/mynewproj/dbaccess.cpp also rollbacked to trunk/myproj/dbaccess.cpp
dbaccess.cpp changes are gone.
I think svndumpfilter cannot distinguish between db/ folder and db* file.

is it bug? or how can i use svndumpfilter correctly?
