Environment variable is not being expanded in config

[Luflosi]

The documentation says that putting

env MYVAR1=a
env MYVAR2=${MYVAR}/${HOME}/b

into the config will set MYVAR2 to a/<path to home directory>/b. Firstly, I think MYVAR should be MYVAR1. But even with that change that, env will output these two lines (and a few others):

MYVAR1=a
MYVAR2=${MYVAR1}/${HOME}/b

This means that MYVAR1 is not being expanded.
