strike-trough on links is failing (if the link is not encapsulated in [[ ]])

XWiki/2.0 syntax is assumed.

Enter the following code.

--http://alink--
--demo--
--[[https://alink]]--

It is displayed as:

http://alink--
demo
https://alink

If you edit it again, the "--" is also added to the source:

--http://alink----
--demo--
--[[https://alink]]--
