OK to repair a few more typos?

Why all the whitespace changes? They don't look correct to me, e.g. many of them look like one space less, which would not be multiples of 4.

Thanks for reporting the typos. I have pushed fixes for them in two commits above. I did not merge the PR because there were a lot of white space changes that didn't make sense, and I didn't want to cherry pick the typos, it was easier to just fix them.

sorry about the whitespace changes. I am using emacs+scimax+emacs Wiki snippet for trailing white space. I will try to debug what went wrong.

I found out the current markdown mode will change space to tabs without:

(setq-default indent-tabs-mode nil)
Why would tabs be a choice for markdown ? I thought most docs avoided tabs at all costs.

Sorry again for adding them.
