* Simplify regular expressions (see below)
* Remove unneeded `parseYAML()` wrapper
* Remove unused callback argument

Regular expression simplifications include:

* Changing trailing `*?$/` to `*$/` because non-greedy matching to the
  end of a line will not change behavior
* Change regexp beginnings like `/^(?:property:?\s*)?[^.\[]+` to the
  equivalent `/[^.\]]+`
* For regular expressions changed per the above, remove
  case-insensitivity if it no longer affects the regexp
