Single quotes in description spoil the sake

Steps to reproduce:

1. Create a new rake task with a single quote in the description
2. Import it as a sake task with sake -i
3. Try to see your sake tasks with sake -T
4. Ruby will crash and it will say that it can't parse

Can ruby2ruby produce double quoted output, or escape internal single quotes?

desc "My fancy task with 'strange' behavior"
task :foo do
  # ...
end

Produces a ~/.sake task like this

desc 'My fancy task with 'strange' behavior'
task :foo do
  # ...
end
