Jeff Sharkey 71cb446f01 Add wrapping support to IndentingPrintWriter.
When created with a wrapping width, any content longer than the
requested width will be wrapped onto additional lines.  This supports
use-cases like dumping lots of data with printPair().

Improve documentation and add tests to verify behavior.
