In the commit 1304f50a5b ("tipc: JSON support for showing nametable"),
introduced misalignment in the columns of the printout in non-JSON mode
compare to the list header. Add one space per column to make alignment
with the list header.
before:
$tipc name show
Type Lower Upper Scope Port Node
1 1 1 node 4071367628
after:
$tipc name show
Type Lower Upper Scope Port Node
1 1 1 node 4071367628
