Fails to release bounds on conditional build-depends

[bgamari]

Consider a case like comonad's cabal file:

...

library
  build-depends:
    base                >= 4       && < 5,
    semigroups          >= 0.8.3.1 && < 1,
    tagged              >= 0.7     && < 1,
    transformers        >= 0.2     && < 0.6,
    transformers-compat >= 0.3     && < 1

  if flag(containers)
    build-depends: containers >= 0.3 && < 0.6

...

When jailbreak-cabal is run on this I see the following result:

...

library
    build-depends:
        base -any,
        semigroups -any,
        tagged -any,
        transformers -any,
        transformers-compat -any

    if flag(containers)
        build-depends:
            containers >=0.3 && <0.6
    if flag(contravariant)
        build-depends:
            contravariant >=0.2.0.1 && <2
    if flag(distributive)
        build-depends:
            distributive >=0.2.2 && <1

...

Here we see that jailbreak-cabal did not modify the conditional build-depends.

It seems that this was previously discussed in #7.

Yes, this is a known limitation.
