chattr: manpage tidyups
Tidy up the chattr(1) manpage to completely document all available options, and differentiate those which are read-only early in the manpage as well. * Remove "I" from settable attribute list * add "e" to 2nd list of settable attributes & descriptions * Note that h/E/I/X/Z are readonly * Correct "H" to "h" for huge file attribute description * fix long_name for indexed directory in flags_array Addresses-Red-Hat-Bugzilla: BZ#502971 Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>bitmap-optimize
