The layout breaks when colons are placed in links

Question

Please, see the broken layout here. If you use links that contain two "http"-part like with the links in WayBack Machine, the SO-layout breaks.

The original code was:

Good tutorial [here][1]. See [this part][3] of the GNU screen manual on how to set ACL permissions. Give him whatever permission you think he needs, though I don't think you'd need to change it from the default that's given by `acladd`.

If the first link is broken, please, it is [here.][2]

Arised Question thanks to Kip informing about %3A

Should colons be automatically rendered to %3A?

Answer 1

I fixed the linked article by changing the colon in the URL to %3A. I don't think colons are considered valid URL characters except in ://, and user:pass@ and :portnum. But I think it's still a bug that the server-side markdown is generating such bad html (the client-side preview looks correct).

For the record, here is the markdown source of the page that was giving the problem:

Which gets rendered like this:

Answer 2

ok, we now auto-encode any colons at string position 7 or higher, that are not followed by 2 or more numbers.
