Legalize it :-) After all, with
<?php switch ($var): ?>
<?php case 1: ?>
there's also a newline finishing the switch-clause that's residing
outside the PHP-block. It should be clear, that
<?php switch ($var): ?>
HTML blah blah
<?php case 1: ?>
is illegal. But I guess I grab the point: An empty line is considered
an empty line of HTML rather than an empty line of PHP. So the parser
strips whitespace AFTER a <?php ?> block, but doesn't ignore empty
lines. This behaviour makes sense in most cases but maybe this
switch-whitespace-case one. Never mind, it smells like tweaking the
parser for no big issue, so adding a phrase to the docs will do I
guess.
Thanks for the fast replies, that's really cool!

as Wez already said,
----
<?php switch ($return) ?>
<?php case 1: ?>
----
and
----
<?php switch ($return)
case 1: ?>
----
are not the same things.
first is equal to:
<?php
switch ($return):
echo "\n";
case 1:
?>
and this is invalid syntax.

Now, that's a matter of taste. I code 99% as classes in external files.
So only very little PHP remains in the actual page file, mainly to
arrange the HTML output. Picture this:
<html>
<?php
// here go a couple of PHP code using external
// classfiles that set a $return value
?>
* SOME HTML CODE *
<?php select ($return) ?>
<?php case 1: ?>
* A BUNCH OF HTML CODE *
<?php break ?>
<?php case 2: ?>
* OTHER HTML CODE *
<?php break ?>
...
<? endswitch ?>
* FINAL HTML CODE *
</html>
I currently omit the empty line between the switch and the first case,
yet why is one Newline after the swtich okay, but two Newlines fail
parsing?

just don't open/close php-tags on every line of your script.
<?
switch () {
//as many empty lines as you want.
case 1:
break;
}
?>

Wow, that was fast :-)
Why shouldn't you be allowed to have whitespace between the opening
switch and the first case clause when it's okay to have whitespace
between case clauses and the final case/default clause and endswitch -
unless of cause eliminating this exception means messing up the parser
code?

Actually this is not bug. You can't have anything between
switch()..case.. ever. It's not valid.
This is same as what you tried:
<?php
$var = 1;
switch (1) {
echo " ";
case 1:
echo $var;
}
?>
