This should be just a cosmetic change; but basically change stuff like

    m = orig;
    s = foo();
    ... lots of lines not using s or m ...
    bar(m,s)
    ... more stuff using s ...

to

    ... lots of lines not using s or m ...
    s = foo();
    bar(orig,s)
    ... more stuff using s ...

This is part of few commits to generally clean up the scope and
comprehensibility of the vars within pp_subst
