+ * print_e2fsck_message() prints a message to the user, using
+ * compression techniques and expansions of abbreviations.
+ *
+ * The following % expansions are supported:
+ *
+ * %b <blk> block number
+ * %B <blkcount> integer
+ * %di <dirent>->ino inode number
+ * %dn <dirent>->name string
+ * %D <dir> inode number
+ * %g <group> integer
+ * %i <ino> inode number
+ * %Is <inode> -> i_size
+ * %Ib <inode> -> i_blocks
+ * %Il <inode> -> i_links_count
+ * %Im <inode> -> i_mode
+ * %IM <inode> -> i_mtime
+ * %IF <inode> -> i_faddr
+ * %If <inode> -> i_file_acl
+ * %Id <inode> -> i_dir_acl
+ * %j <ino2> inode number
+ * %N <num>
+ * %p ext2fs_get_pathname of directory <ino>
+ * %P ext2fs_get_pathname of <dirent>->ino with <ino2> as
+ * the containing directory. (If dirent is NULL
+ * then return the pathname of directory <ino2>)
+ * %q ext2fs_get_pathname of directory <dir>
+ * %Q ext2fs_get_pathname of directory <ino> with <dir> as
+ * the containing directory.
+ *
+ * The following '@' expansions are supported:
+ *
+ * @b block
+ * @B bitmap
+ * @C conflicts with some other fs block
+ * @i inode
+ * @D deleted
+ * @d directory
+ * @e entry
+ * @E Entry '%Dn' in %p (%i)
+ * @F for @i %i (%Q) is
+ * @g group
+ * @l lost+found
+ * @L is a link
+ * @u unattached
+ * @r root inode
+ * @z zero-length
