sequencer: move "else" keyword onto the same line as preceding brace

sequencer: move "else" keyword onto the same line as preceding brace

It is the current coding style of the Git project to write

	if (...) {
		...
	} else {
		...
	}

instead of putting the closing brace and the "else" keyword on separate
lines.
