Generated links to default template files

Hi,

I found a small issue in http://api.drupal.org/api/function/template_preprocess_page/6 ,
where links labeled "page.tpl.php" lead to http://api.drupal.org/api/file/themes/pushbutton/page.tpl.php/6 ,
while the text mentions a reference to "modules/system/page.tpl.php" .

The documentation being generated by doxygen, I realised that the problem was caused by homonym files, inherent to Drupal OO-like architecture.
I'm not aware of a way to specify destination links for doxygen, in source documentation blocks.

I did a few tests with my doxygen (v. 1.5.8), and I found that the double quotes around full path name prevented the link to be generated.

Replacing patterns like

... own copy of page.tpl.php. The default is located inside "modules/system/page.tpl.php"

with

... own copy of @em page.tpl.php. The default is located inside modules/system/page.tpl.php

shows the first filename "emphasized" (no link there anyway with my doxygen version, maybe because of duplicate names), and the second as a link to the intended destination page.
Another option would be:

... own copy of @em "page.tpl.php". The default is located inside modules/system/page.tpl.php

which would prevent the false link if it was generated on your platform.

I enclose the corresponding patches.

I filed this issue in Drupal project, and not documentation, because the origin and solution stays in core source files, not the website.
