Subject: [PATCH] Kill getDiskSizeInfo() function. Instead of making an extra
 function call, packing return values in key'd values of a table and then use
 two table indexing operations, just call util.df(".") directly from
 FileInfo:formatDiskSizeInfo() and use its two return values appropriately.
