Avoid source properties in psyntax
* module/ice-9/psyntax.scm (source-annotation): Only return source properties from syntax objects. (source-wrap): Don't look for source properties. (expand-macro): Rebuild source properties on macro output via source-wrap, not source properties. Only annotate head of a chain of pairs. (strip): Here's the only use of set-source-properties!: when stripping a syntax object to a datum. (macroexpand): If the input expression is not a syntax object, eagerly extract its source properties. (datum->syntax): Fix case in which source is given as an alist. * module/ice-9/psyntax-pp.scm: Regenerate.
