I doubt it's a sed bug. (It has them, but not something this basic).

You're doing it right.

Check:

	that you really have a space and a tab in there, rather than
	  some cut/paste accident with a bunch of spaces and no tab

	that the data file is a nice clean UNIX file - no DOS line endings
	  in it. The latter will show as ^M at the end of the line in vi.
	  "od -c" will also make this obvious.
	  How did the data file get to your UNIX box?
	  Maybe you need to dos2unix the data file.
