The rewrite her discards the functions that did direct, recursive expansion of macro values. Instead, the parser now pushes the macro definition string over to a stack of buffers for the lexer. This way, macro expansion gets access to all parsing machinery. This isn't a small change, but the result is simpler than before (I think). It passes the entire test suite, including the four tests added with the previous commit that were failing before.
