Reword the discussion of the built-in userdiff patterns to make it more natural to precede it with a discussion about the semantics of pattern matching, instead of assuming that it follows right after the "diff.tex.xfuncname" example which now immediately precedes it. This will make a follow-up commit smaller.

Good changes. The current text, which dates back to ae7aa499 (Document custom hunk header selection, 2007-07-08), may have been adequate back when there were only "java" and "tex" built-in patterns but not anymore. I may (or may not) give the series a second pass to collect independently salvageable bits, and if I did so, this would be one of those that would be gleaned. Thanks.
