Hi,

browse-url-of-dired-file signals an error if the user attempts to
browse one of the special file names '.' or '..'.  I see no reason
why it should not be possible to browse these file names like any
other directory file name.  Below is a patch together with a change
log entry.


2011-03-11  Ralph Schleicher  <rs <at> ralph-schleicher.de>

	* net/browse-url.el (browse-url-of-dired-file): Enable browsing
	of special file names `.' and `..'.
