XF 2.2 Quoting text from custom bb code should wrap quoted text in bbcode

[Jawsh]

For instance,

[tag]Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi volutpat viverra interdum. Fusce et nibh non leo ultricies maximus id non sapien.[/tag]
Curabitur imperdiet felis sit amet pellentesque commodo. Nulla convallis vulputate auctor.

Any part of the first sentence would render with the tag quote.

[tag]Fusce et nibh non leo ultricies maximus id non sapien.[/tag]

Any part of the first sentence with subsequent out of bbcode text would render accordingly.

[tag]Fusce et nibh non leo ultricies maximus id non sapien.[/tag]
Curabitur imperdiet felis sit amet pellentesque commodo.

What would be the easiest way to accomplish this? I'm looking at the controller plugin Quote.php and Str/Formatter.php but it seems very rigid.
