Today if you write a hashtag project link in Phriction then it appears as nothing more than a normal hashtag, but it should be a link/reference to the project being referred to.
Project hashtag links don't work if they're followed by a period, e.g. Remarkup versus Remarkup.

You know what it was? I wrote "#project." since it was at the end of a sentence. I'm not sure if that's a parser bug for the tags or just intended behavior.
I personally found it a little strange.
See D8703 for previous work. We currently assume that #security. is a slug named security. (with a period), and allow this as a side effect of allowing slugs like #blog.phacility.com, which seems reasonable (e.g., allowing project names to be domain names or domain-like strings).
Consuming the period when it isn't followed by anything seems worse than treating it as punctuation, though -- that is, we should consume security.com from #security.com, but only security from #security.
