Wrap lines longer than option "width".

This is WIP. References #247. Opening the pull request per #247 (comment).

I thought a bit about this and I think in principle your approach seems to be a reasonable solution. However, I think in order for the PR to be merged, there are quite a few things I would like to change. Do you want to do that yourself or is it too tedious for you and you are happy if I do it? I am open to both. If you don't want to do it yourself, I'd ask you to close this PR and create a new PR to another (yet to be created) branch. Here's a sketch of I think needs to be done:

• rebasing on master and resolve merge conflicts.
• apply styler to the PR.
• replace base R calls to apply() and friends with purrr equivalents.
• replace the repeat() and while() statements with recursions.
• documenting with roxygen.
• adding unit tests and thinking of exceptions.
• some minor code refactoring (i.e. don't define functions within functions, function re-naming, exposing of the width argument).

Thanks for looking into this. If you're willing to do the rest, I'm happy to hand it over.

I don't quite follow what you want me to do, though. Do you want me to create a new branch at krivit/styler, make no changes to it at all, and then initiate a PR from that?

[lorenzwalthert]

Ok, fine. No, I just meant that you create a PR to r-lib/styler#line-with, which I will merge immediately. Then, I will continue to develop from there before I merge the changes into master. If I merged this PR, it would take effect to master immediately, which I prefre not to happen.

I just did the work for you @krivit. Welcomed to follow-up on the development and test. Thanks for the initial work.

[krivit]

@lorenzwalthert , I see. Thanks!
