Two reasons whey the links in markdown wikis are not updated:
1. The markdown link pattern is wrong, should be []() rather than [][];
2. The logic of getting wiki local var cannot get correct wiki index as:
a. the renamed file's buffer is removed and %:p would return empty
b. the function that gets the wiki local var depends on buffer's %:p
value to find the wiki it belongs to and it would always return -1
and result in the default option values instead the user's option
The fix is
1. fix the markdown link pattern regex;
2. keep the renamed file's buffer open during the period of updating the link
