Subject: Using File.open block to manage svnadmin dump stream

While working on a script to manage dumps from a subversion repository 
of mine, I found that when I used a File.open block to work with the 
stream returned by svnadmin dump, I would get errors regarding a 
malformed header in the dump file. For instance:

# The following block results in bad dump files, not accepted by 
svnadmin load
File.open("path/to/todays/dumpfile", "a") do |file|
  file << `svnadmin dump "path/to/repository" -r #{revision} 
--incremental`
end

# However, a strait command expression does work, like
`svnadmin dump "path/to/repository" -r #{revision} --incremental >> 
"path/to/todays/dumpfile"`

Might anyone know why the use of a File.open block would result in a 
dump file not accepted by svnadmin load, while a strait command 
expression works? I tried using the << and write methods of File, but 
still no luck. Perhaps I don't understand a more appropriate way to 
write the stream?

Thanks for taking a look.
Brad
