One simply way to merge tags is to delete one of the documents. Users could do this themselves, then all previous tags can be merged automatically.
Lets say I want to rename A to B. Both A.md and B.md exist. If I try to rename A to B I get a message, "add all content from A.md to B.md, delete A.md and retry". Once A.md ceases to exist I can trivially rename all references A to B.
