I'm a bit lost here. Are we referring to
if (expr) {
...
} else {
...
}
versus
if (expr) {
...
}
else {
...
}
?
If so the former is usual style. People do add code which does the latter,
but it tends to get fixed up later on when someone else does some work on
the same code.

This is
if (expr1 &&
expr2)
versus
if (expr1
&& expr2)
the former is more common and is, IMO, more readable.
The latter can be handy sometimes to prevent an 80-col overflow in the
first line.
