Fix: VimwikiTOC is broken against headers with link (Issue #182)
Problem: VimwikiTOC and follow_link do not support header (anchor) with link in their body Solution: - VimwikiTOC (easy): Create function base.vim s:clean_header_text that converts [DESC](URL) -> DESC - follow_link (hard): -- [[URL]]: was already working due to punctuation removal. -- [DESC](URL): Search for a potential `]([^)]*)` after every character
