Always eager to improve the syntactic beauty of my sources, I wondered
how this indentation style looks like so I peeked at the implementation
of the Format-module, which seems to be written by you.

Indeed, this style is obviously very coherent: one can find anything
from 1, 2 to 4 spaces of indentation consistently applied throughout
the whole file, e.g.:

  let add_queue x q =
   let c = Cons {head = x; tail = Nil} in
   ...

  let pp_print_as state n s =
    if state.pp_curr_depth < state.pp_max_boxes
    ...

  let pp_print_newline state () =
      pp_flush_queue state true; state.pp_flush_function ()
      ...

The rules can be easily inferred: one space if the function body starts
with a "let", two if it starts with "if" and four in any other case.

Is it this kind of consistency you mean in the Programming Guidelines? :-)

Best regards,
Markus Mottl

  P.S.: Sorry for my sarcasm! As usual I couldn't resist... ;)
