Subject: [PATCH] babel: now including source code block arguments w/source
 name on export

  This change provides for better export of named source-code blocks,
  with specific support for more attractive html export.  The arguments
  are included with the source code name, and both the source code name
  and code body are wrapped in a div to support styling with css.  For
  example the following CSS can be used to associate a source-code block
  name with it's code body, and to slightly indent the body.

.org-src-container {
  border-left: 4px solid gray;
  padding: 0.5em 0.5em 0.5em 1em; }
  .org-src-container pre {
    margin-left: 1em; }
