On the whole I'd prefer us to move to using spaces for indentation (so
-Wleading-whitespace=spaces), but certainly =blanks corresponds better to
the current intent.

I think the "for -ftabstop=8" bit in the comments is only relevant for
-Wleading-whitespace-1.c, not this test, where the tabstop is irrelevant
when only spaces are expected.
The patch is OK with those comments fixed.
