Example of how indentation creeps into function definitions

Steps to reproduce:

1. rails new hippo --database=postgresql
2. edit gemfile to add fx, bundle install
3. bundle exec rails generate fx:function square
4. edit the function definition file
5. bundle exec rake db:create db:migrate (this writes the initial function definition to schema.rb)

---

Up to this point, everything is fine. However, if we use db:schema:load, fx will read the function definition from schema.rb and recreate the function with 6 spaces within the function definition itself.

Then whenever the schema is dumped again, such as after running db:migrate for other migrations, the function definition will be written to schema.rb with the internal spaces as well as the formatting spaces, for a total of 12 spaces:

6. bundle exec rake db:schema:load db:migrate (0a4f9d)

7. repeat step 6, each time 6 new spaces are added. (052f76)

8. Switch fx to my patched version (459314)

9. repeat step 6, each time nothing is added (NO DIFF, because schema.rb does not change)
