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;
}
?>

Description:

Hi there

This is a very minor bug concerning the structure of a source code
rather than its functionality. It's been dealt with in Bug #13387, yet
the case was closed back then when it seems to have been fixed in
4.2.0-dev. It's back in 4.3.3.

Here are some examples:

Example 1, okay:
<?php switch ($var): ?>
<?php case 1: ?>
<?php dothis() ?>
<?php endswitch ?>

Example 2, okay:
<?php switch ($var) { ?>

<?php case 1: ?>
<?php dothis() ?>

<?php } ?>

Example 3, syntax error:
<?php switch ($var): ?>

<?php case 1: ?>
<?php dothis() ?>

<?php endswitch ?>

The parser doesn't seem to like whitespace in HTML between switch and
case.

When mixing PHP and HTML code, the syntax in example 3 can improve
readablility.

Reproduce code:
---------------
<?php $var = 1 ?>
<?php switch ($var): ?>

<?php case 1: ?>
<?php print $var ?>

<?php endswitch ?>

Expected result:
----------------
1

Actual result:
--------------
Parse error: parse error, expecting `T_ENDSWITCH' or `T_CASE' or
`T_DEFAULT' in .../test.php on line 4
