Suppose the shebang-less script is being run by an earlier version
of bash.  Won't the new patch radically change the behavior of of
such programs?

Or, say I'm running a bash from /home/myhome/bin/bash (even though my
normal shell is /bin/bash).  Those options would have to be reset in
the new, child script, no?  So again, how would the difference in
behaviors affect a user?

Does posix define the behavior of a child script with no interp-line?
