No such problems here, ever.
Whereever I put my installation on the server, no matter which folder, subdomain, etc., I never had to change anything in .htaccess. Maybe a very specific server configuration? For me, on about 5 different hosts this problem never appeared.
Seriously...can we have that in the manual???
The manual is a wiki and everyone can contribute. So if you feel that this is something that needs to be added, feel free to help. Seriously.
