re chet_ramey:
So excuse my thoughtless uneducated comment, please.
Thanks for pointing to the corresponding standard passage.

re Stéphane:
Hm, i see that even shipout scripts of mine do not do this right, regarding
set -o noglob.
And not working with names that contain a LF, even then.

How is eaccess(3) implemented?  I do not see an eaccess(2) system call?
Interesting can of worms.  Will improve my script workaround.
