ports/152499: Redirections in es may take effect in the shell itself

[Harald Hanche-Olsen]

"The vendor" no longer exists, and has not existed for years.

The bug does not appear on any other architectures I know.

It follows that if the port is to remain in the FreeBSD ports tree, it
needs to be fixed by a patch.

If no one else does it, I will investigate the problem myself when I
find some spare time (not this week, but maybe next week).

Therefore, I believe the right action for now is to reopen the PR
until I or someone else finds a solution and comes up with a patch.
If you agree, please reopen.
