bug#63780: Reversing the grep message output type matching binary files (without the -a option added) changed from stdout to stderr

[Paul Jackson]

That "2> >(...)" syntax forprocess substition off the explicitly specified file
descriptor 2 output surprised me.

Only now, thanks to this example, do I realize that this usage is implied
in the two zshmisc(1) REDIRECTION section sentences beginning with:

>> If one of the above is preceded by a digit  ...

and 

>> The various forms of process substitution ... are often used together with 
>> redirection ...

Once again, as I have known for nearly a half century, man pages are sometimes
written to only be understood by those who already know what they are reading..
