git-ls-files --unmerged implies --stages: ?

Hi,

I wonder why git-ls-files --unmerged implies --stages. One nice use case for this command is to edit all the conflicting files after a failed merge, i.e.

$ vi $(git-ls-files --unmerged)

except I need a pipe to throw out all the cruft in there.

Does anybody depend on that implication, or do I need to add a "no-stages" option, or am I blind and there's a better way to do this?
