Server Command "/whitelist list" doesn't display the full list of players

When using the command "/whitelist list" there is a point where not all of the players are listed. A screenshot provide shows the list holds 17 players name however displays 10 full names and 1 cut off name "eli".

Note: Names are blacken for Confidential reasoning.

I suspect it would happen to other commands that need to list players name, however no testing has been done to prove this.

What I expected to happen was...:
The full 17 (or more) players names are listed

What actually happened was...:
Not all are listed (depending on amount of characters in list).

Steps to Reproduce:
1. Enter SMP as Op.
2. Add names to whitetlist via command or whitelist.txt
3. Use command in chat "/whitelist list"
4. Depending on the amount of people in whitelist will depend on the output of displayable names
