profiling: improve '+' markup of nested lines

The display of nested lines was very non-obvious and made it look like sort
didn't work.

The '+' immediately before CallCount was not related to the CallCount and did
not mean plus in any integer sense.

The '+' before module looked like a part of the module name and not like ascii art.

Instead we now only show '+' before the module name but add a space to make it
look more like ascii art.
