	* libguile/eval.c: Sorted include files alphabetically.

	(scm_m_begin): Added comment.

	(scm_m_or): Use ASSERT_SYNTAX to signal syntax errors.  Avoid
	unnecessary consing when creating the memoized code.

	(iqq, scm_m_quasiquote, scm_m_quote): Use ASSERT_SYNTAX to signal
	syntax errors.  Be more specific about the kind of error that was
	detected.

	(scm_m_quote, unmemocopy): As an optimization, vector constants
	are now inserted unquoted into the memoized code.  During
	unmemoization the quotes are added again to provide syntactically
	correct code.

	* test-suite/tests/syntax.test (exception:missing/extra-expr,
	exception:missing/extra-expr-misc): Renamed
	exception:missing/extra-expr to exception:missing/extra-expr-misc.

	(exception:missing/extra-expr-syntax,
	exception:missing/extra-expr): Renamed
