just a few typo fixes, nothing major

[corinnebosley]

Conda-gitenv is so cool! I didn't really understand what it was before, and now I do, and it's awesome.

Anyway, this is just a few typo fixes which I felt I had to apply to appease my OCD nature. I may make some alterations to a few sections of the readme later on (I found the first paragraph and the notes section a little confusing) but for now these are purely cosmetic changes.

@pelson @bjlittle I am hoping to get these teeny tiny changes merged pretty quick. It's just typo fixes is all.

[corinnebosley]

Right well that's not good is it? This was supposed to be simple.

Well I don't know what's going on here. When I run that test locally it passes. I'll keep digging...

The error is something like:

It is a concern, but not for this PR.
