New Comment:
Spaces are indeed significant. Here's why.
<? switch($var){ ?>
<? case "alpha":
break;
}?>
Is equivalent to
<? switch($var) {
print " ";
break;
}?>
The two spaces outside the PHP blocks are a valid two character HTML block!
Whereas:
<? switch($var){ ?>
<? case "alpha":
break;
}?>
is equivalent to:
<? switch($var){
case "alpha":
break;
}?>
which is valid.
Vlad was wrong, the bug is not valid :)

Observe that the spaces are significant.
This doesn't work:
<? switch($var){ ?>
<? case "alpha":
break;
}?>
This does!:
<? switch($var){ ?>
<? case "alpha":
break;
}?>
I suppose that the interpreter converts text outside <? ?> to echo statements, so that
the first code block is equivalent to:
<? switch($var){
echo ' ';
case "alpha":
break;
}?>
This code block gave the same parse error as the first one!
(Expecting T_CASE or T_DEFAULT or '}')

The bug is valid - if you close and reopen the PHP tags between the switch and the
case statement, it is going to bark at you. It shouldn't.
This does not work:
<? switch($var){ ?>
<? case "alpha":
break;
}?>
This does:
<? switch($var){
case "alpha":
break;
}?>
Why in the world would anyone do that, is a whole other issue, still they probably
expect to be able to do just that. If they can't, we either need to document it as
such, (thus re-classify this as documentation problem) or fix it. I do not know what
it takes to fix that, but it is a valid report nevertheless.
Unbogusifying...

Which style I use, the "classical" style (using {}) or the "alternative" style (using
: and endswitch), doesn't matter; the problem is the same.
Sniper's comment about using <? ?> several times is surely justified when having
one-line code as in his example, but when it comes to multi-line code, there is an
issue of readability. I think that script A below is easier to read than script B.
Don't you?
--- begin script A ---
<? switch($var): ?>
<? case "alpha": ?>
<p>Alpha</p>
<? break; ?>
<? case "beta": ?>
<p>Beta</p>
<? break; ?>
<? default: ?>
<p>Default</p>
<? break; ?>
<? endswitch; ?>
--- end script A ---
--- begin script B ---
<?
switch($var):
case "alpha": ?>
<p>Alpha</p>
<? break;
case "beta": ?>
<p>Beta</p>
<? break;
default: ?>
<p>Default</p>
<? break;
endswitch; ?>
--- end script B ---

Use the {} instead of the : / endswitch;
ie.
<?php
switch ($value) {
case: ?>
<p>Alpha</p>
<?php
break;
}
?>
And anyway, using <? ?> too much is really not good idea.
This is just stupid: <? some code ?><? more code?><? code..?>

Section 7.4 in the FAQ is a little bit related.
Should perhaps the ending for a block of PHP-code be "?>" followed by any number of
white-space characters?
