missing --- in generated file

[bleuse]

I'm using a step where I generate a file containing the sequence ---.

The step code boils down to:

- generate-file:
  - write_in:
    - $${location}/file
    - |
      some content for my file
      ---
      some injected value: $${key}

I expect the generated file to be (if key is set to e.g. 42):

some content for my file
---
some injected value: 42

However, the generated content is (see the missing --- sequence):

some content for my file

some injected value: 42

This seems to be related to the code managing steps (step.rb) where a gsub is performed to remove --- no matter where it is located.
