None of these conditionals are indented properly, please fix this up.
Both conditionals and function calls that span multiple lines must use
the column after the openning parenthesis of the initial line as the
left justification of subsequent lines.

I see what you're doing, just using TAB characters exclusively to
ident, don't do that.  You must use the appropriate combination of
TAB and space characters to achieve the correct indentaiton.
