Getting a strange output when formatting a Rational value in trunk.

% ruby -v -e 'p "%.1f" % 1.2r'
ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0]
"1.2"

% ruby -v -e 'p "%.1f" % 1.2r'
ruby 2.2.0dev (2014-08-19 trunk 47220) [x86_64-darwin13]
"6.0"

In this case 1.2r inspects into 6/5 and then the % takes its first letter, I guess?

Maybe broken yesterday somewhere around here? https://github.com/ruby/ruby/commit/1d196e0d2bd99590d03a73d7e59aa87f7266f8e3
