MD014 only considers the `$` sign, is this intentional? about markdownlint

[DavidAnson]

I think the rule does not recognize hash as a dollar alternative. (The unconditional rendering of hash lines as comments is a GitHub behavior.) I'd be inclined to make what's probably a simple change to address this in the rule, but I worry about the hash/comment scenario being far more common than scenarios with hash/admin behavior. In other words, I worry that a simple fix may make things worse instead of better. This is the first time I remember the issue coming up, so the problem you raise may be relatively rare. I'm open to more input on the matter.

Yes, that is by far the most common

I've seen it, but very rarely. You're right

It may be worth it though to support the % symbol used by C Shell and variants,
but I'm not familiar with those. See https://superuser.com/questions/57575/what-is-the-origin-of-the-unix-dollar-prompt
