Improve diff message "no files"

When a changeset contains only minor modifications (blank line, whitespace changes …) and the matching "ignore" checkboxes are selected, Trac outputs a confusing message:
whereas the actual message should be something like "(No visible changes)", as the changeset does contain files, but the selected diff options lead to an empty diff.
This is confusing especially as Trac conveniently keeps track of the user diff preferences from one diff to another - which implies that a user can get a "(No files)" message as soon as he wants a diff.
