The ascii-art graph in the BlockLatencyHistogramInfo
documentation doesn't render correctly in either the HTML
or the manpage output, because in both cases the whitespace
is collapsed.

Use the '|' format that emits a literal 'example' block
so the graph is displayed correctly.

Plain text and PDF output is just as bad.  Suggest "doesn't render
correctly, because the whitespace is collapsed".

Wow, we're acquiring a second use of the '|' feature.

It's actually broken, because the doc generator puts each | line in its
own @example environment.

Doesn't really matter, because PATCH 26 replaces it by rST markup that
actually works.  A note in the commit message could make sense, though.

But instead of making it differently broken until PATCH 26 fixes it for
good, I'd simply leave it broken until then :)

If you decide to keep the patch: can we keep the table aligned with the
preceding paragraph?  Like this:

   # |      5|           *
   # |      4|           *
   # |      3| *         *
   # |      2| *         *    *
   # |      1| *    *    *    *
   # |       +------------------
   # |           10   50   100

IIRC I need to fix it early, because without the '|' prefix it's
a syntax error in rST because of the inconsistent indent. (Otherwise
I probably wouldn't have noticed it at all.)
