should we worry about the case where bash has been symlinked to ash
and the thing loops?
As long as it works with mac,cygwin,90% linuxes, I'm still leaning
towards simply changing the shebang to #!/bin/bash. I am happy to assume
BSD,IRIX,AIX,fringe linux folks will be capable enough to modify it
themselves if that's needed.
