[PATCH] lisp/net/browse-url.el allow fragments in file: urls

This fixes the current behavior of browse-url--non-html-file-url-p and
makes it possible to open file:// urls that end with a #fragment. The
current behavior results in a nasty side effect where opening a file
with browse-url-emacs that has a fragment causes any invocation of
call-process to fail because the fragment is not handled correctly.

Best!
Tom
