Fix AST matcher documentation.

Fix a bug in the matcher docs where callExpr(on(...)) was in the examples,
but didn't work (on() only works for memberCallExpr).

Fix a bug in the doc dump script that was introduced in r231575 when
removing a regexp capture without adapting the code that uses the
captures.
