ChangeLog, mke2fs.8.in, mke2fs.c, tune2fs.8.in, tune2fs.c:
  tune2fs.c, mke2fs.c, tune2fs.8.in, mke2fs.8.in: Change user interface
  	so that -J is used to specify journal options, and -j is used to
  	request creation of a journal using default values.  (This is a UI
  	change, but we haven't done a formal release, and it makes things much
  	more consistent with the rest of the options out there.)
  tune2fs.c: Add support for removing a filesystem from an external
  	journal; we correctly remove the filesystem UUID from the external
  	journal's filesystem list.
