Add cabal init --no-comments option to config file

[Lysxia]

I'd like to use cabal init non-interactively. How can I configure its default behavior? In particular I'd like to set the --no-comments option in the config file.

Alas in ~/.cabal/config, in the init section, I see an interactive: option but not a comments: one.

It's a valid feature request. Shouldn't be hard to implement.

I fail to find another ticket where someone wanted a config field for author and stuff like that, but we suggested they use arguments and maybe wrap a cabal init call with those arguments in a script…

I did a quick experiment here: ulysses4ever@1d3c743

It's easy but it needs couple more pushes that I don't know when I can get to, so please take over if you feel like it:

• it needs a test
• it's not clear which init flags we want to allow: besides no-comments it seemed reasonable to allow quiet, simple and minimal (the last one implies no-comments btw). But maybe author and email too? Something else?

[Lysxia]

When I use cabal init it already knows my name (author and email). I can't find out where that's stored though.

@Lysxia it fetches it from your git config. One can imagine a setup without git available. It would be a very rare setup of course.
