`COMPOSE_IGNORE_ORPHANS=1` does not work (Docker

[akauppi]

File: compose/reference/envvars.md

COMPOSE_IGNORE_ORPHANS When enabled, Compose doesn’t try to detect orphaned containers for the project.

Supported values: true or 1, to enable, false or 0, to disable. Defaults to: 0.

Reality:

• only true works, 1 doesn't

I did not want to suggest a change to the docs since I don't know if the implementation - or the docs - are at fault.
