userdiff: two simplifications of patterns for rust

- Do not enforce (but assume) syntactic correctness of language
  constructs that go into hunk headers: we only want to ensure that
  the keywords actually are words and not just the initial part of
  some identifier.

- In the word regex, match numbers only when they begin with a digit,
  but then be liberal in what follows, assuming that the text that is
  matched is syntactially correct.
