To accommodate "-" in function names would amount
to using a POSIX extension, so we'd have to use bash.

Can you confirm that those tests succeed when you replace
#!/bin/sh with #!/bin/bash in the test scripts that use init.sh?

If so, the proposed re-exec approach should end up solving the problem.
Now we have to determine which replacement shell to use.
One way would be to write something similar to posix-shell.m4
that tests for the added capability.  Or perhaps just perform
the test "live" every time we run init.sh.
