How about this (pre-)patch? With the `:literal' attr., the content of the
block is exported "as is", with all manual formatting preserved.

I have made some modifications in the horizontal and vertical spaces (in
case :literal is used), because the em does not seem the correct length
to me. The em equals the font size in points, and, vertically, it would
not equal a blank line (line spacing is usually 120% of the em), so it's
safest to use \baselineskip. Thus, \vspace*{\baselineskip} is identical
to leaving an empty line. As for the horizontal space, the em is greater
than the normal space. The closest thing would be to use
\fontdimen2\font. So, if one puts 6 manual spaces (with the spacebar
key), it is exported as \hspace*{6\fontdimen2\font}
