To me the distinction is largely in the eyes of the user. Most modern programming languages have facilities to achieve a wide range of goals. I think the question "is there a programming language made specifically for X?", is far less important than the question "is there a language in which I can do X, efficiently/securely/scalable/...?" There are some languages which are clearly domain specific. Markdown is not a general computing language.
