This is further progress towards a metaprogramming system in a form
similar to Elaborator Reflection or Template Haskell, but trying to
avoid leaking too many implementation details of the elaborator itself.
This is the result of running the command:
$ find . -name '*.idr' -type f -exec sed -i -E 's/\s+$//' {} +
I confirmed before running it that this would not affect any markdown
formatting in documentation comments.
