I thought the point of introducing the new "precious" class of
paths, in addition to the current "tracked", "ignored, untracked,
and expendable", "not ignored and untracked", is so that people can
do "git clean -x -d -f" and expect the ".config" that is marked as
"precious" to stay.  Before their Git learned the precious class, if
they marked ".config" as "ignored, untracked, and expendable", then
such an invocation of "clean" would have removed it, but if they add
it to the new "precious" class, their expectation ought to be that
precious ones are not removed, no?  Otherwise I am not quite sure
what the point of adding such a new protection is.
