Update regex to identify yaml delimiters #12

Closed apoorv74 closed 6 years ago

The existing regex will detect lines that do not contain # character E.g. grep("^#?---", "---") will return 1. To make it more fail safe, we can usegrep("^#{1}-{3} ?$", f)`

Was not sure whether uncommented YAML front matter should be accepted or not, makes sense according to the specification. Hence, closing it.
