Subject: [PATCH] glr2.cc: kill trailing white spaces

Fixes several calc tests.

Tests 566 568 570 657 still fail because of a name clash when using
%parse-param:

    calc.cc:1395:85: error: declaration shadows a field of 'calc::parser' [-Werror,-Wshadow]
    void glr_state::destroy (char const* yymsg, calc::parser& yyparser, semantic_value *result, int *count, int *nerrs)
                                                                                        ^
    calc.hh:441:21: note: previous declaration is here
        semantic_value *result;
                        ^

* data/skeletons/glr2.cc: Fix indentation/trailing spaces.
