<!-- 

Search for [[wikilink]] instead of "wikilink" when finding backlinks to prevent false positives: Otherwise, for a note whose filename/title is "now", every note containing the word "now" would be appended as a backlink)

Regex not working for notes with colons on filename because hugo .File.BaseFileName returns a string with colons removed.
