A related (?) issue:

emacs -q --no-site-file --eval "(setq calendar-setup 'calendar-only)"
M-x calendar
C-h k d                ; in the calendar buffer

doesn't show the help, but gives the error "Window is dedicated to
`*Calendar*'".

It seems to be a `with-output-to-temp-buffer' problem - if called
from a dedicated window it barfs when trying to display the temp
buffer.
