But that does not work: it turns out that $0 is always "/bin/bash" in
.bashenv (or just "bash" if called as "bash script"). Apparently $0 is
only set to the script name after .bashenv has been processed, and it
isn't in any other environment variable either.

I took another look at this -- this is not the first request to make the
shell script filename available in startup files -- and I don't think
that it will break anything or add an incompatibility to set $0 as
requested here.
