No, if you think about it you should see that preprocessing it via cpp
would not have been desirable.  I don't know exactly how he did it,
but one possibility would have been to temporarily disable the # directives,
except for the ones that #defined the Algolish macros, and preprocess just
that, the reenable the remaining # directives.  The way cpp works, probably
some additional cleanup would have been necessary afterwards.
