Actually it doesn't "fail" with both bash and zsh.

The original problem was how to put "ksh" (implying NetBSD /bin/ksh)
specific code in a separate file, no doubt so that the same ~/.* files
can be used with both /bin/sh and /bin/ksh.  The above test is more than
sufficient to achieve that limited goal.  Obviously if you throw bash
and/or zsh into the equation then things get more complicated, but not
impossibly so.

Yes, there is.  Please look at my complete ~/.profile.  It is 100%
portable across all the platforms I use regularly and no doubt still
portable to many of the older systems I no longer use.  I have no doubt
the mechanisms I use can easily be extended to handle zsh if necessary,
and I have been thinking of cleaning it up somewhat so that I can treat
all the POSIX compatible shells in the same manner and thus hopefully
ease some of the maintenance overhead.
