Merge pull request #117 from gwelymernans/master

Don't split a container if it will cause the alignment to go haywire.
Use explicit continued indent sizes.

If the '--indent-size' flag is 2, then the 'indent_word' size is also 2.
This breaks the formatting requirement that the continued indentation be
a multiple of 4 spaces. Instead of trying to calculate this, make it
explicit.
