top: enable alternate '+' placement with collapsed pid

Currently, except for tasks that have no parents, when
a process' children are collapsed the '+' indicator is
shown in the first position within that COMMAND field.

This commit simply provides for indenting the '+' char
so it displays next to that program name/command line.
