PHP syntax highlight does not support namespaces

[GoogleCodeExporter]

Code is:

<pre><code>catch (\PDOException $e) {
  $error = $e-&gt;getMessage();
</code></pre>

P in the class name should be the same colour as the rest of the name, only \ 
should be different. But the result is:

<pre class="default prettyprint prettyprinted" style=""><code><span 
class="kwd">catch</span><span class="pln"> </span><span 
class="pun">(</span><span class="pln">\P</span><span 
class="typ">DOException</span><span class="pln"> $e</span><span 
class="pun">)</span><span class="pln"> </span><span class="pun">{</span><span 
class="pln">
  $error </span><span class="pun">=</span><span class="pln"> $e</span><span class="pun">-&gt;</span><span class="pln">getMessage</span><span class="pun">();</span></code></pre>

I'm using Stack Exchange version 
(http://drupal.stackexchange.com/a/91283/16495) - probably latest stable 
release. It happens on all major browsers.

So \Exception shows up fine because \E is treated as plain followed by xception also as plain, then both get combined as plain. But \PDoException is parsed as: \P plain, then DoException is treated as type name.

This bug is not specific to PHP, it's the way the generic highlighter incorrectly handles an escape token followed by a type names (starting with an upper case letter).

It's related to 11c71c4d which fixed issue #144
