That's a very selfish attitude ;-)  Pay attention to what others are
doing while you are working on this topic (hint: do not limit your
check to 'master', but make sure your changes also work well when
merged to 'next' and 'pu'---make a trial merge or two and run test
suite, for example).

I am not sure how you would avoid indent-with-space with "cat".
With the use of "sed" like I showed above to spell the left margin
explicitly out, we can---I am not saying it's the only way, but I do
not think of a clean way to do the same with "cat".
