Alternate ENVIRON syntax does not work on Linux

[a740g]

According to the ENVIRON wiki, ENVIRON can be used like

ENVIRON "myParamter=myValue"

or

ENVIRON "myParamter myValue"

However, on Linux (and possibly macOS) only the space version works. Nothing is set when using the equals sign version of the syntax.
