Great points Thanks.

hlines are preservable with the :hlines header argument, see the example
below [1].

Were working on integrating the babel documentation in the org-mode
documentation which should really help in terms of making these more
exotic header arguments accessible/discoverable to users.

Good catch, this has been fixed.

Again, thanks for pointing this out.  This has been fixed for results
which already have an indented

  #+results:

line, for the first time a block is run the results will not be indented
currently, although it would probably be worthwhile to default to
indenting the results to the same level as the code block -- I'll add
this as a TODO.

See the example below [1], is it sufficient to squeeze the #+results
line in between the #+attr_latex line and the table?  If not I'll update
the results handling so that we allow preservation of comment lines
between #+results and it's contents.
