Lots of extraneous commas in Guide

[alexreg]

It should be evident where these occurrences are: http://doc.crates.io/guide.html

It is not evident, that's why they're there 😉 Specifics would be appreciated.

Okay, here are some examples of bad commas and other punctuation issues:

Cargo is a tool that allows Rust projects to declare their various dependencies, and ensure that you’ll always get a repeatable build.

This is called a manifest, and it contains all of the metadata that Cargo needs to compile your project. – semicolon preferable to , and

Now, if regex gets updated, we will still build with the same revision, until we choose to cargo update. (last comma)

This would be bad, because we want reproducible builds.

When we’re ready to opt in to a new version of the library, Cargo can re-calculate the dependencies, and update things for us: (last comma)

You find a bug in conduit, and you want to write a patch.

I'm addressing most of these and some others, but I disagree with:

I think those are fine.

Fair enough. Thanks for taking this on board at least. I know there were some other ones too, so glad you found some.
