This is certainly not right. You've made gbt_bpchar_consistent
work identically to gbt_text_consistent, but it needs to implement
a test equivalent to bpchareq, ie ignore trailing spaces in both
inputs.
The minimum-effort fix would be to apply rtrim1 to both strings
in gbt_bpchar_consistent, but I wonder if we can improve on that
by pushing the ignore-trailing-spaces behavior further down.
I didn't look yet at whether gbt_var_consistent can support
any type-specific behavior.
