  chattr.1.in:
  lsattr.1.in: Change "version" to "version/generation number".
  chattr.1.in: Fix stupid file vs filesystem typo.
  tune2fs.c Fix spelling error (spare vs sparse).
  mke2fs.c (PRS): Add safety check to make sure the number of blocks
  	doesn't exceed 32 bits on a 64 bit machine.
  chattr.c: Random cleanup; file-only variables are now static.  Options

  lsattr.c: Random cleanup; file-only variables are now static.  The -l
  	"long" listing has been changed to look nicer.  Options names have
  	been renamed to be more descriptive.
