Support curly braces

[anka-213]

Cabal files apparently allows writing curly braces around blocks, which confuses implicit-hie. For example, this file: https://github.com/ivan-m/graphviz/blob/42dbb6312d7edf789d7055079de7b4fa099a4acc/graphviz.cabal#L59

Library {

-- ...

will generate a hie.yaml file like this

cradle:
  cabal:
    - path: "./"
      component: "graphviz:lib:{"

# ...

instead of the expected

cradle:
  cabal:
    - path: "./"
      component: "lib:graphviz"

# ...

Is cabal indent insensitive within curly blocks?

[anka-213]

What does index sensitive mean?

[Avi-D-coder]

oops, indent insensitive.

Just hit this trying to load the Graphviz library in to HLS. No idea why it uses those braces, but, well, if Cabal accepts them...

Unfortunately, I don't have any time to work on this in the next two weeks.

I ran into this with brittany: https://github.com/lspitzner/brittany/blob/4d064db674203626fe5011d10874fcbc335ec9b1/brittany.cabal#L47

I'll take a look this weekend.
