I think this is fine.

I am guessing that you are saying it is wrong to force wt-status.c
to include pathspec.h before including wt-status.h; I am fine with
that.

This is a tangent, but the above is different from saying that with
a single liner test.c that has

    #include "wt-status.h"

your compilation "cc -c test.c" should succeed.  But for that goal,
direct inclusion of <stdio.h> to wt-status.h is also iffy.  We
include the system headers from git-compat-util.h because some
platforms are picky about order of inclusion of system header files
and definitions of feature test macros.

Right now, the codebase is correct only because it is NOT our goal
to guarantee that such a single-liner test.c file compiles.
Instead, everybody is instructed to #include "git-compat-util.h" as
the first thing, either directly or indirectly.

So in that sense, we should also remove that inclusion from
wt-status.h, I think.

Thanks.
