Wrong parsing of links if the link contain parentheses

[rabuzarus]

[ifwizz Link](https://ifwizz.de/klub-karisma-(2008-de).html) will be parsed as ifwizz Link [0].html)

Works in HEX format https://ifwizz.de/klub-karisma-%282008-de%29.html
Of course mdp also displays it in HEX format when it is in HEX format, which is ugly even though correct.

Does not work by escapes. The source

[ifwizz Link](https://ifwizz.de/klub-karisma-\(2008-de\).html)

gets rendered as

ifwizz Link [0].html)

[0] https://ifwizz.de/klub-karisma-\(2008-de\

I think it is not good that the escapes get interpreted wrong. But it is good that HEX format works.
