balance_leaf() in fs/reiserfs/do_balan.c

Example picked totally at random:

	set_le_ih_k_offset(ih,
			   le_ih_k_offset(ih) +
			   (tb->
			    lbytes <<
			    (is_indirect_le_ih
			     (ih) ? tb->tb_sb->
			     s_blocksize_bits -
			     UNFM_P_SHIFT :
			     0)));

See how everything is nicely aligned to 80 cols?


Generally, don't look at this function after having a good lunch you want 
to keep. You have been warned.
