Word Documents; inserting Wiki text with LineFeed or Carriage Return character fails

Inserting wiki text into a Word Document fails if the text includes a single Line Feed or Carriage Return and not the New Line combination of Carriage Return and Line Feed.

.AddWiki("line 1" & vbLf & "line 2")

Note, this works fine if using a New Line, as in vbNewline.

.AddWiki("line 1" & vbNewLine & "line 2")
