But it has nothing to do with the GUI preferences: it applies to the 
command-line version of R as well.

What about ?help did you not understand? It says

           chmhelp = getOption("chmhelp"),
           ...
  chmhelp: logical (or 'NULL'). Only relevant under Windows. If 'TRUE'
           the Compiled HTML version of the help on the topic will be
           shown in a help viewer.

so you need to set options(chmhelp=FALSE): it is up to you where you set 
it.
