Actually, I used a suggestion from before, which worked, but I  
haven't rechecked this section (see below) after the problem emerged.  
So I may have to get back on this.

It is possible to fix this by adding, as you suggest, so the example  
becomes:
----
\version "2.11.33"
\paper{ ragged-right=##t }
\relative c' {
  \time 25/16
  \set beatGrouping = #'(3 4 3 4 4 3 4)
  #(override-auto-beam-setting '(end * * 25 16) 3 16)
  #(override-auto-beam-setting '(end * * 25 16) 7 16)
  #(override-auto-beam-setting '(end * * 25 16) 10 16)
  #(override-auto-beam-setting '(end * * 25 16) 14 16)
  #(override-auto-beam-setting '(end * * 25 16) 18 16)
  #(override-auto-beam-setting '(end * * 25 16) 21 16)
  c16 c c   e8 e16 e

}

Great! Thank you!

However, if I change the added line to:
  \set beatGrouping = #'(2 1 2 2 2 1 2 2 2 2 2 1 2 2)
then I would want the secondary beams to break accordingly, but it  
doesn't.

Perhaps this can illustrate what I am looking for:

Instead of all the above, I would to be able to write something like  
(in pseudo-code)
  \set grouping = #'(((2 1) (2 2)); ((2 1) (2 2)); ((2 2) (2 1) (2 2)))
The ";" will translate into dotted bars "|" (with the measure). The  
top level grouping will describe break structure between beam groups.  
The level below will describe break structure between the secondary  
beams levels. And one might put in more levels for addition beaming  
(1/32th notes and higher).

And the next step in interfacing would be to be able to indicate this  
in \time or \times command.
