We process in groups, so rules in core.excludesfile are in one group,
those in $GIT_DIR/info/exclude in another group. Negative patterns
only has effects within their group, so !*out in .../exclude can't
revert *.out in core.excludesfile. Probably implementation limitation,
not by design..

But even if we flatten them into one group, i'm not sure you can
achieve that. The patterns would be

!*.out
*.out

"!*.out" has nothing to revert because it's before "*.out".
