I'm running into an internal error with the syntax/module-reader
library with the given test program, and wanted to double check with
someone else before committing the fix upstream.
The test file is:
https://gist.github.com/dyoo/5272982
When I run this under an unpatched module reader, I see the following error:
128-110-73-138:Desktop dyoo$ raco test prepend-lang-line.rkt

My proposed patch is:
https://github.com/dyoo/racket/commit/9322570e3e0210b99ec8a85dca52b62b4dde66fd
Does this look ok? Also, if I do push this upstream, how do I attach
my test file so it gets run as part of the DrDr regression suite?
