getpwent for indoes?

[Peter Klosky]

A little more investigation has shown that du() and ls() may in fact
tell the truth about file size under 4.2 file systems in terms
of the number of blocks used; looks like there are more
fields available from stat() than in historic systems such
as System V.  I wondered why our 4.2 manual did not list the du()
bug present in System V as a "limitation."  Now I know.
So stat() may tell the truth about some things, though perhaps
not the whole truth.

Of course, I still don't know how to cat a file by inode number
under 4.2; in specific, the concept of cylinder groups has me
confused.  Is there just one i-list or many on a given file system?
