Base URL is forbidden on .info domains.

Repeatable: Always
Steps to repeat:
1. Get access to a web server with a domain in .info zone. E.g. example.info
2. Download drupal 6.8 and unpack it into web server's document root
3. Point your browser to the base URL of the server: (http://example.info/)

Expected Results:
First page ("Choose language") of drupal installer should appear.

Actual Results:
Server denies the request:
---
Forbidden
You don't have permission to access / on this server.
Apache/1.3.41 Server at example.info Port 80
---

However, visiting http://example.info/index.php works fine.

It seems that the reason is in the drupal's .htaccess file.
It contains the following line:

<FilesMatch "\.(engine|inc|info|install|module|profile|test|po|sh|.*sql|theme|tpl(\.php)?|xtmpl|svn-base)$|^(code-style\.pl|Entries.*|Repository|Root|Tag|Template|all-wcprops|entries|format)$">

It should block access to files with .info extension. E.g. http://server/path/file.info
However, it also blocks URLs like: http://example.info/
