Process substitution issues when using /dev/fd

[IgorTodorovskiIBM]

z/OS offers both /dev/fdN and /dev/fd/N. It seems that on some systems, /dev/fd is a character device and in others it's a directory. Bash assumes it is always a directory, so this can introduce problems on systems where it's a character device.

Another issue is that the character devices are untagged and as such there is no autoconversion.
