The three shells in your list are all variants of the same base. It's
like using three different releases of bash. The other two aren't
shells. C is a reasonable comparison, but there are other differences
in how the languages are parsed and executed.

I haven't done an extensive investigation. It's not really a significant
issue. It's important enough that bash, ksh, and zsh agree. We don't
need more incompatibilities between the major shells.
