There are exactly two places in our json doc comments where we
use the markup accepted by the texi doc generator where a '|' in
the first line of a doc comment means the line should be emitted
as a literal block (fixed-width font, whitespace preserved).

Since we use this syntax so rarely, instead of making the rST
generator support it, instead just convert the two uses to
rST-format literal blocks, which are indented and introduced
with '::'.

(The rST generator doesn't complain about the old style syntax,
it just emits it with the '|' and with the whitespace not
preserved, which looks odd, but means we can safely leave this
change until after we've stopped generating texinfo.)

Has always been pretty broken, though: each line ends up in its own
@example environment.  See doc-good.texi.

Also, we should not reinvent what reST already provides.

In other words, the recent switch to the reST generator messed these
examples up, and this commit tidies up.

Could exploit that reST is the Perl of ASCII-based markups, and write

   #        For the example above, @bins may be something like [3, 1, 5, 2],
   #        and corresponding histogram looks like::
   #
   #        5|           *
   #        4|           *
   #        3| *         *
   #        2| *         *    *
   #        1| *    *    *    *
   #         +------------------
   #             10   50   100
   #
   # Since: 4.0
   ##

Matter of taste.  I find both similarly arcane.
