Returning from a three weeks journey, my favorite is #2 but call the
function list_dialog_multisel(). Then follows #4, but I would put
the optional parameter at the start, ie 
 
 list_dialog(["singlesel"|"multisel",] prompt, list, button_label1, ...)

Finally, Tony's #4 will do, too - I really like to have this
function in a new release.  A global variable setting the default
value of the optional parameter like $list_dialog_select_mode also
would be a good idea.
