Currently "x" acts buffer-wide.

Your suggestion is to hide the files that are in the same state as the
file at point.  

If there are marked files, then potentially a super-set of marked files
could get hidden.  This "superset" behaviour will surprise the user -
"Why does even un-marked files get hidden?"

I am little bit hesitant to re-work the patch.
