Previously, our hashtag parser would indiscriminately replace hashtag-like text with hashtag HTML -- including in places it shouldn't have, like inside code blocks. Along with the v1.7.0 changes to writeas/saturday, this fixes that and closes #6. As a bonus, strings of #spaceless#hashtags#in#a#row are now rendered correctly.
