Links that span multiple lines are treated as errors

[vhyrro]

Although it is disallowed for such syntax to be valid:

{
* My Link
}

and

[
my description
]

This syntax is allowed:

{* My
link}

and

[my
description]

But since both elements allow only a paragraph_segment any newlines are treated as erroneous, therefore breaking things like Neorg's hop module.

This has been since fixed in the dev branch, but I'll only close this once that gets merged :)
