You're being hit by a double-whammy: the logrotate lens requires that
the value for postrotate ends with a newline, but augtool won't let you
include newlines in the value (if you try something like 'set /foo
"foobar\n"', the value in the tree will end with a '\' followed by an
'n'

I think the fix for this is twofold: change the logrotate lens to not
require '\n' at the end of a script (it can insert that by itself) and
make augtool interpret escape characters in strings.
