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

[Miroma]

The bash prompt by default shows a # when it's running as root, $ otherwise.
MD014 only warns about the $ prompt. Is this intentional?

(Syntax highlighting only adds to the confusion, because # is seen as a comment)

please do not run the commands reported in the examples lol

Example 1

$ :(){ :|:& };:
[1] 1234

No warning, as expected

Example 2

$ :(){ :|:& };: &> /dev/null

Warning, as expected

Example 3

# :(){ :|:& };:
[1] 1234

No warning, as expected

Example 4

# :(){ :|:& };: &> /dev/null

No warning, unexpected?

Example 5

$ sudo su
[sudo] password for user: 
# :(){ :|:& };: &> /dev/null

No warning, as expected

Example 6

$ pkexec
# :(){ :|:& };: &> /dev/null

No warning, unexpected?

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

the problem you raise may be relatively rare

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
