If you want results embedded into a paragraph, then I would suggest
using an inline code block.  Regular code blocks are "blocks" in that
they will break paragraphs and are treated (in my mind) more like
figures than inline elements.

Thanks for the patch, I would not want this behavior on by default
because I think the results in the Org-mode file are less visually
pleasing than when results are padded with spaces.  Perhaps this
behavior could be controlled through a new header argument which would
default to the current behavior.

A similar issue regarding the insertion of spaces through repeated
evaluation and removal of results of a code block has been discussed
recently.  I'm pushing up a small fix for that issue now.
