I agree that it is a bug. Names of zones, users, groups, projects,
etc. should not be truncated unless the command allows me to specify
the column width. I get what I deserve if I tell a command to be
imprecise but the precision is important.

Don't worry about the alignment. Sure it will be ugly, but ugly is
better than wrong. Take vmstat, df, or any number of other commands
as a precedent. I stopped using sar at a time when all the numbers
started running together and I could no longer trust that the output

How about a variant of:
ps -o zone,user,pid,args -u fred
This may produce ugly yet correct output (assuming that all zones use
the same name service - may break anyway if ps is "too smart"). You
can adjust the columns to match the -flZ output if desired.
