Usage of dangling ] messes up the parser.

STR:

• Use ]] in your string.
• Observe the markdown output.

Expected:

• ]] should come up normally.

Actual:

• ]] doesn't come up.

Demo. Compare it with remarkable

Why I care ?

A Punjabi font uses roman characters to form Punjabi alphabets. It uses ]] for what is know as full stop in Punjabi. It is broken now after I moved from remarkable to snarkdown. I love the perf and size of library, and I understand why this might not be considered to be fixed, but I thought it's worth the shot!

It's very hard to understand the regex but I guess

/(
  (?:^|\n+)
  (?:\n---+|\* \*(?: \*)+)\n) |
  (?:^```(\w*)\n([\s\S]*?)\n```$) |
  ((?:(?:^|\n+)(?:\t|  {2,}).+)+\n*) |
  ((?:(?:^|\n)([>*+-]|\d+\.)\s+.*)+) |

          vvvvv ----> this might be related 
  (?:\!\[([^\]]*?)\]\(([^\)]+?)\)) |

  (\[)|(\](?:\(([^\)]+?)\))?) |
  (?:(?:^|\n+)([^\s].*)\n(\-{3,}|={3,})(?:\n+|$)) |
  (?:(?:^|\n+)(#{1,3})\s*(.+)(?:\n+|$)) |
  (?:`([^`].*?)`) |
  (  \n\n*|\n{2,}|__|\*\*|[_*])
/gm,

PS: Are you considering breaking up the regex into RegExp objects to make it easier to work with it?

@bogas04 impossible to break up the regex due to filesize constraints, but perhaps having a commented out multiline version above would work.
