[PATCH] maint: use consistent cpp indentation in all .c files

[Jim Meyering]

Back in the days of the CVS repository, I had a hook that
would run cppi and reject any commit that introduced a
CPP indentation/nesting mismatch, i.e.,

This would be rejected,

#if FOO
#define BAR 1
#endif

This would pass:

#if FOO
# define BAR 1
#endif

Obviously not a big deal above, but if you have the
misfortune to deal with code ifdef'd to 8 or 9 levels
(I did) then this tool becomes absolutely essential.

Anyway, since the switch to git, it's been a while
since I checked coreutils' src/*.c, and so today I
found a couple of violations.  Here are fixes:

[for good measure, here's a new snapshot of cppi:

 or the old one:
