Spaces: See [here](https://github.com/mongodb/mongo/blob/master/rpm/init.d-mongod#L25-26) and [here](https://github.com/mongodb/mongo/blob/master/rpm/mongod.conf#L3-13) for examples of where this is used and not consistent.

Allcaps - that's more of a convention than requirement, since many *nix config files are sourced by another script, it makes it easier to identify a variable. It's pretty standard across many packages etc. And you're right, it might be something more for a JIRA than a doc update.
