I don't think there is need for an empty line after the opening brace
of a function, in any case.
The newline + indent should be enough to make it readable. I don't see
why starting with a blank line for longer functions would improve
readability. (I'm not talking about blank lines further along the
function to group statements and thus add structure and improve
readability and overview)
