It looks like my original patch was never integrated.  The code below makes tangling multi-line variable work by using Lua's multi-line string syntax ([=[ ... ]=]) instead of the python-like but invalid """.

Likewise, it doesn't change the single line behavior.

Testing is pretty straightforward:  pass a multi-line variable in as a header argument, tangle the file and try to load it.  Before == syntax error and after == code loads and runs.
