Hello,

The following patch extends :float attribute to src blocks (so they are
on par with tables and images). It also slightly changes syntax for this
attribute:

  |        | Old           | New      |
  |--------+---------------+----------|
  | Tables | :float table  | :float t |
  | Images | :float figure | :float t | 

With this patch :float attribute also accepts a nil value in all cases,
preventing any floating mechanism, even if a caption is provided. In
particular, it replaces :long-listing attribute for src blocks:

  |            | Old             | New        |
  |------------+-----------------+------------|
  | Src blocks | :long-listing t | :float nil |

Overall, it makes :float syntax a bit more regular, but it implies some
gotchas.

WDYT?


Regards,
