"xheader" was meant to be shorthand for "expanded output header"

It's meant to say don't print anything past the column spec, e.g.:

-[ RECORD 1 ]----+
n | 42
long_column_name | xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-[ RECORD 2 ]----+
n | 210
long_column_name | xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
