Subject: [PATCH] More fine tuning of the mime of the opened file

In fba90677fcc9ccf0e6f5efe75e7446703d669d36 we introduced a "if we're
told this is a text file let's check the mime of the content only since
text files never fail to open".

This extends it to anything that inherits from text now, so if you
rename a PDF file to bla.php it still tries to open as a pdf first and
if that files as a php file
