Parse multiline values

[joelvh]

These minor changes allow for successfully parsing config variables exported from Heroku.

@bkeepers any interest in merging this? Fixes multi-line value parsing, such as using heroku config:pull to parse multi-line values from Heroku. This was not working without these updates.

Thanks!

@bkeepers is there no interest in merging this? It addresses the issue of not being able to use a .env file dumped from Heroku which have multi-line values, which I'm sure many people deal with. Thanks!

👋 @joelvh !

Apologies for this languishing. I'm part of a trio of new maintainers and our first order of business is getting caught up on the outstanding and stale PRs. I just wanted to let you know I'm reviewing it shortly, and to thank you for the contribution.
