Expressions not interpolated if they occur on parser buffer boundaries

[cmlenz]

If an expression ($var or ${var}) in a template occurrs at a buffer boundary of the XML parser, the parser will emit two TEXT events instead of one. The Template class doesn't coalesce adjacent text events before parsing out expressions, so it will the expression will not be interpolated and evaluated. Instead you get events such as ${v and ar}.

Should be fixed in [185].
