That should work for the use case at hand, but we should scan the source
for occurrences of the tools to see if other git commands need to be
wrapped as well.  This doesn't also cover 'uname' from my report, which
should be looked into as well (when is it needed? is it a fatal error if
it's missing? etc.)
