We'd need something like this on top.  Our top-level .gitattributes
defines the default whitespace rules with !indent-with-non-tab and
enables indent-with-non-tab for specific file suffixes like .[ch],
but git-gui/.gitattributes enforces indent-with-non-tab for all
files.

Another thing with this series (and this follow-up) is if we want to
start treating git-gui/ as just a subdirectory without no plan to
feed our changes to the "upstream".  I am actually OK with that, as
the "upstream" we merge (with -Xsubtree merge strategy) from does
not seem to be very active and responsive these days.
