I personally ident multi-line conditionals in "if" and "while" with
tabs to the keyword level, then pad with spaces so 2nd+ line starts in
the same column as first part of the condition (i.e one column to the
right from opening paren). Logical operation goes to EOL.

Also with multi-line condition and single-line body I often use braces
to separate them better.
