I can imagine that this could improve readability a little bit. Maybe if
one uses same fancy ide/editor that can fold code blocks like functions
and conditionals, this patch could make the code prettier.

The patch seems pretty trivial and doesn't change any actual code, so
I don't see hard resons for rejecting it.
