Here is Markdown list of very long items:

❯ cat ./dash-separated-link-list.md
- [Link 1](#link-1) - Description of line 1.
- [Link 2](#link-2) - A very long description for the second link in the list. That description is more than 80 characters wide.
- [This is a very long title, pointing to an awesome article on incredible stuff we're not used to see everyday](#link-3) - Line #3's description.
- [Link number three](#this-is-a-very-long-url-that-is-pointing-to-a-really-really-great-website) - Fourth description.

It properly renders into 4 items:

• Link 1 - Description of line 1.
• Link 2 - A very long description for the second link in the list. That description is more than 80 characters wide.
• This is a very long title, pointing to an awesome article on incredible stuff we're not used to see everyday - Line #3's description.
• Link number three - Fourth description.

But it does not comply with the MD013 rule:

❯ markdownlint ./dash-separated-link-list.md
(...)
./dash-separated-link-list.md:2:81 MD013/line-length Line length [Expected: 80; Actual: 128]
./dash-separated-link-list.md:3:81 MD013/line-length Line length [Expected: 80; Actual: 146]
./dash-separated-link-list.md:4:81 MD013/line-length Line length [Expected: 80; Actual: 119]

Now I'd like to limit each line to 80 characters. My cleaned-up markdown now looks like:

❯ cat ./dash-separated-link-list-80-chars.md
- [Link 1](#link-1) - Description of line 1.
- [Link 2](#link-2) - A very long description for the second link in the list.
  That description is more than 80 characters wide.
- [This is a very long title, pointing to an awesome article on incredible
  stuff we're not used to see everyday](#link-3) - Line \#3's description.
- [Link number
  three](#this-is-a-very-long-url-that-is-pointing-to-a-really-really-great-website) -
  Fourth description.

But this makes markdownlint unhappy:

❯ markdownlint ./dash-separated-link-list-80-chars.md
(...)
./dash-separated-link-list-80-chars.md:7:81 MD013/line-length Line length [Expected: 80; Actual: 86]

The thing is I can't simply split the 4th item before the middle dash. The layout below:

- [Link 1](#link-1) - Description of line 1.
- [Link 2](#link-2) - A very long description for the second link in the list.
  That description is more than 80 characters wide.
- [This is a very long title, pointing to an awesome article on incredible
  stuff we're not used to see everyday](#link-3) - Line \#3's description.
- [Link number
  three](#this-is-a-very-long-url-that-is-pointing-to-a-really-really-great-website)
  - Fourth description.

rightfully renders the last description into its own sub-list:

• Link 1 - Description of line 1.
• Link 2 - A very long description for the second link in the list. That description is more than 80 characters wide.
• This is a very long title, pointing to an awesome article on incredible stuff we're not used to see everyday - Line #3's description.
• Link number three
  • Fourth description.

This is an edge-case, and I'd like to have markdownlint detect and allow for trailing spaces and dashes in long lines.

For reference, here the version I'm using:

❯ markdownlint --version
0.23.2

For the record, this edge-case is currently being discussed at:
