Column widths don't have to be hardcoded.  For example, we compute the width of the "Target Id"
column dynamically.  See target_id_col_width in print_thread_info_1.  So maybe all we need is to
base the "current" column's width depend on the wcwidth of the character used.  Even if we end up
with a narrower character by default, the user can always configure their style to use a wider
one, so it seems to me like we should do that regardless.

I'm undecided myself between backhand and Right Arrow (➡️) or one of the latter's variants.  I like backhand
and I think its use is quite widespread for this.  OTOH, an arrow might look a bit more "professional".
Not sure, I've not really tried it any of this.
