editfiles wildcard question

[ANDERSON RUSSELL D (ANDY)]

Can someone help me with using wildcards in editfiles?
I have a bunch of files such as one.txt, two.txt, three.txt and need to change 
a line in all of them.
When I use this, I get an error: "Multiple filenames in editfiles"
This leads me to believe it wants to resolve to a single filename?

editfiles:
  { /tmp/testdir
  Include *.txt
  Exclude bla.*
  Ignore "."
  Ignore ".."
  Recurse 6
  ReplaceAll "one" With "two"
  }

Thanks
