there are many ways in which you can force a markup parser (not just  
Wikka's) to do things it was not designed to, that doesn't mean we  
encourage our users to take these cases as the rule.
Sorry if it sounds disappointing.

let me stress it again. Literal newlines in the links regex are not  
officially supported.
The table markup parser is pretty robust, but it currently doesn't  
support multiline elements (such as lists) within table cells. This is  
why using a literal \n within a table cell (as well as within a link)  
is not supported.

No, \n is *not* officially supported within a forced link. I was not  
behind the decision to losen the link regex, I would be happy to  
enforce a stricter markup.
I agree that leaving undocumented formatter options lurking around may  
be an annoying source of confusion.

the table row syntax is line based. Tables (as multi-row elements) are  
by definition multilines.
literal linebreaks are allowed within text formatters (such as  
**strong** and //emphasis//), <<floats<<,  %%code blocks%%
