Just FYI, from the coding doco:

> The comment on a function is much clearer if you use the argument names to speak about the argument values. The variable name itself should be lower case, but write it in upper case when you are speaking about the value rather than the variable itself. Thus, "the inode number NODE_NUM" rather than "an inode".
