If the user has "savefig.extension : auto" (deprecated) in their (old… 
…) matplotlibrc, it will be copied into "savefig.format", where "auto" is not a supported choice. This will fix it so it becomes "png" if it's currently set to "auto". This bug discovered as part of #1530, though it doesn't fix it.
