   That's why I commented that something was bogus.  Here it is
again:
law.Bliss> cat /tmp/t.sh
#!/bin/bash -u
echo -e "Hello World\n"

law.Bliss> t.sh
/usr/bin/bash: - : invalid option
Usage:  /usr/bin/bash [GNU long option] [option] ...
       /usr/bin/bash [GNU long option] [option] script-file ...
GNU long options:

The reason the above fails... (I got it to work).. is that if there is a space
on the line after the "-u", that also fails.

I didn't deliberately put one there, but that it no longer handles
separate options is an evolution of software devolution.

But NOTE -- the above error claims it is coming from /usr/bin/bash.
That's not my login shell nor on the shebang line.

That's cygwin-black-magic... converting all /bin paths to /usr/bin...even
shells?...

I'm aware of that -- I was noting that the alternate ways of invoking it
made a difference.  Not that I didn't understand why.
