ChangeLog, Makefile.in, mke2fs.8.in, mke2fs.c, tune2fs.8.in, tune2fs.c:
  tune2fs.c (main): Add a new option -O which allows the user to set and
  	clear certain "safe" filsystem feature flags.  Currently, the only
  	ones which are supported for modification are sparse_superblock and
  	filetype.
  mke2fs.c (PRS): Add new option -O which allows the user to request
  	filesystems with specific filesystem options.  By default on 2.2 and
  	later systems, create filesystems that have both file type information
  	and sparse superblocks.
