Allow user to set indent level and parsing status of type comments

Why do you need this feature?

I was checking typed_ast and i wanted to know which parts changed and
implement that parts to astor. But there was no flags for --type-comments
False.

Also it can be handy to have an indention option to change it for fitting
tree into the terminal width.

Sorry, I do not understand you. typed_ast does not have such features as multiline dump() and CLI. What relation is this have with the --type-comments flag?

As for fitting tree into the terminal width, the current indentation is 3 spaces. Changing it to 2 spaces will not save much horisontal space, and 1-space indentation is not particularly readable.

I do not want to complicate this tiny feature. If you want more control on the output, you can write a small Python script which calls ast.dump() programmatically.

Making more configurable isn't making it complicated. It is just improving users control over it by indentation and parsing option.

I don't have any strong opinion either way, so it looks like we need to wait until someone else will ask for this.
