(1) open local html file in browser:

• rox /usr/share/doc/app/userguide-en.html
• rox -U file:///usr/share/doc/app/userguide-en.html

(2) soap error:

• rox -U file:///usr/share/doc/app/userguide-en.html#anchor

(3) delayed_error "File doesn't exist, or I can't access it":

• rox file:///usr/share/doc/app/userguide-en.html
• rox file:///usr/share/doc/app/userguide-en.html#anchor
• /usr/share/doc/app/userguide-en.html#anchor

ROX-Filer after this patch

Case (2) isn't an error anymore: file opens in http browser, which understands the #anchor suffix. No change to case (3), which remains an error.
