Set the prefix of all Denote buffers

The user option denote-buffer-name-prefix specifies the text used as a prefix of all buffer names generated by Denote. This applies to the buffer of query links, backlinks, denote-grep, denote-dired, as well as those affected by denote-rename-buffer-mode:

• Add a query link.
• The backlinks’ buffer.
• Use denote-grep to search inside files.
• Display filtered and sorted files with denote-sort-dired or denote-dired.
• Automatically rename Denote file buffers.

By default, the value of denote-buffer-name-prefix is ‘"[D] "’. Users can set it to any string they want, such as ‘"<Denote> "’, or even an empty string to not have any such prefix.
