Some snippets should indent when expanded

The four snippets(giv, the, whe, and) don't get indented properly when expanded.

`(yas-indent-line 'fixed)` should not be set for the four snippets. After deleting the line from the snippet file, the indent works as expected. I also update the README with markdown.
