Transpilation does not work with semi-complex YAML files

[JJ]

Describe the bug

As soon as the yaml file is a bit complex, it breaks down using transpiled files with an "Unknown Ussage" message. The problem is that it includes both types of quotes, and there's no way to further quote it, it simply breaks. This file, for instance:

---
entidad:
  - src/bankaccount/model.rs
  - src/bankcard/model.rs
  - src/bankfund/model.rs
  - src/controller/model.rs
  - src/paymentgroup/model.rs
  - src/savinggroup/model.rs
  - src/user/model.rs
  - src/utils/model.rs

test:
  - src/bankaccount/test_galvanic.rs
  - src/bankcard/test_galvanic.rs
  - src/bankfund/test.rs
  - src/controller/test.rs
  - src/paymentgroup/test.rs
  - src/savinggroup/test.rs
  - src/user/test_galvanic.rs
  - src/utils/test_galvanic.rs

lenguaje: rust 

fichero_tareas:
  - make.toml

Will create this transpiled file:

entidad.[0]="src/bankaccount/model.rs"
entidad.[1]="src/bankcard/model.rs"
entidad.[2]="src/bankfund/model.rs"
entidad.[3]="src/controller/model.rs"
entidad.[4]="src/paymentgroup/model.rs"
entidad.[5]="src/savinggroup/model.rs"
entidad.[6]="src/user/model.rs"
entidad.[7]="src/utils/model.rs"
test.[0]="src/bankaccount/test_galvanic.rs"
test.[1]="src/bankcard/test_galvanic.rs"
test.[2]="src/bankfund/test.rs"
test.[3]="src/controller/test.rs"
test.[4]="src/paymentgroup/test.rs"
test.[5]="src/savinggroup/test.rs"
test.[6]="src/user/test_galvanic.rs"
test.[7]="src/utils/test_galvanic.rs"
lenguaje="rust"
fichero_tareas.[0]="make.toml"

Which, when expanded, will result in something like:

ysh -T 'entidad.[0]="src/bankaccount/model.rs"' 'entidad.[1]="src/bankcard/model.rs"' 'entidad.[2]="src/bankfund/model.rs"' 'entidad.[3]="src/controller/model.rs"' 'entidad.[4]="src/paymentgroup/model.rs"' 'entidad.[5]="src/savinggroup/model.rs"' 'entidad.[6]="src/user/model.rs"' 'entidad.[7]="src/utils/model.rs"' 'test.[0]="src/bankaccount/test_galvanic.rs"' 'test.[1]="src/bankcard/test_galvanic.rs"' 'test.[2]="src/bankfund/test.rs"' 'test.[3]="src/controller/test.rs"' 'test.[4]="src/paymentgroup/test.rs"' 'test.[5]="src/savinggroup/test.rs"' 'test.[6]="src/user/test_galvanic.rs"' 'test.[7]="src/utils/test_galvanic.rs"' 'lenguaje="rust' '"' 'fichero_tareas.[0]="make.toml"' -q lenguaje 
Unknown Ussage!

With the resulting error. I've tried to escape it usint the @q quote, but it still does not work.
