. Print the column headers centered (except for the left-aligned
TYPE header) using a different header for architectures where
sizeof(uintptr_t) is not four.
. Consistently do not print a '0x' prefix for hexadecimal values.
. Separate columns by a single space character.
. Pad the columns presenting an address or offset enough to hold
their respective largest value.
. Do not restrict the output to unknown file types, inodes and
sockets; allow displaying of pipes, fifos, kqueues and crypto file
descriptors too.
- Shorten an overly long line by removing a cast of printf's return
value to void.
