#17 command line get utilities print blank line after output

[Greg White]

eget/pvget print a blank line after printing a table or name-value system (possibly others too). Eg

$ eget -s testNTNameValue -a columns=3
name0 0.852942
name1 1.39481
name2 2.57148
<- Blank line
$

This complicates construction of shell pipes.

The bug is probably in the Helper for printing a named-value system at [1].
