MD019 - Multiple spaces after hash on atx style header

Tags: headers, atx, spaces

Aliases: no-multiple-space-atx

This rule is triggered when more than one space is used to separate the header text from the hash characters in an atx style header:

#  Header 1

##  Header 2

To fix this, separate the header text from the hash character by a single space:

# Header 1

## Header 2
