    lexer: Change the pipeline to allow more flexible use of macros.
    
    Frans Houweling reported that a use of macros in the following way:
    
        DEFINE !dir() "/directory/to/my/work" !ENDDEFINE.
        GET FILE=!dir + "/filename.sav".
    
    did not work properly with the newly implemented PSPP macro facility.
    Indeed, PSPP has until now implemented string concatenation early in the
    lexical pipeline, before macro expansion, so that the above could
    not work.  This commit reworks it so that string concatenation happens
    as the last stage in lexical analysis.  It allows the above syntax
    to work as expected.
