We indent continuation lines with just one more tab.

Well, yes, but not super important.

See above.

This is actually a lot less readable than it was.

Our convention now is to put the \ just one space after the line.

Only one more tab indentation for the continuation lines.

So, I've marked your patch as Changes Requested in patchwork. Feel free
to submit an updated version that takes into account the comments if
you're interested.

Thanks!
