From: Marc-André Lureau <mlureau@redhat.com>
This adds xfuncname and word_regex patterns for Rust, a quite popular programming language. It also includes test cases for the xfuncname regex (t4018) and updated documentation.
The word_regex pattern finds identifiers, integers, floats and operators, according to the Rust Reference Book.
