I was not able to reproduce it with the recipe above, and it's strange
that that should have any effect -- `tab-width' is automatically
buffer-local.
But I'm able to reproduce it with "emacs -Q /tmp/a.sh" and then
`M-: (setq tab-width 4 sh-basic-offset 4) RET'.

I don't get exactly what you're getting, but I'm getting something very
close to it. For instance, with 16, the buffer becomes completely blank.
