problem with Mutt macro instructions in man page

[prosolutions at gmx.net]

There is a problem with the following .muttrc macro commands as given in the bogofilter man page:

       macro index d "<enter-command>unset wait_key\n\
       <pipe-entry>bogofilter -n\n\
       <enter-command>set wait_key\n\
       <delete-message>" "delete message as non-spam"
       macro index \ed "<enter-command>unset wait_key\n\
       <pipe-entry>bogofilter -s\n\
       <enter-command>set wait_key\n\
       <delete-message>" "delete message as spam"

This produces the following in the help index (?) in Mutt:

<Esc>d              M <enter-command>unset wait_... delete message as spam
d                   M <enter-command>unset wait... delete message as non-spam
