I omitted 300 lines of range-diff, which is not exactly illuminating
in this case.  I wonder if there is a way to turn it off when it is
not helping automatically...

These sound somewhat strange, as the above makes it sound as if we
are recording eolinfo for something (we never record eolinfo of
anything anywhere).

	eolinfo:index::
	eolinfo:worktree::
        	The <eolinfo> (see the description of the `--eol` option) of
                the contents in the index or in the worktree for the path

perhaps?  I dunno.

Likewise, eolattr comes from the attribute subsystem and not
recorded in the index.  It is more like

	eolattr:
                The <eolattr> (see the description of the `--eol` option)
                that applies to the path.

Because attribute applies to the path, it applies equally to both
what is in the index and what is in the working tree.

As ls-tree already uses %(path) for it, this is probably OK
(otherwise we would probably have called it %(pathname)).
