Changing INFOPATH does seem to work. I guess Emacs ignores the 'PATH'
component of INFOPATH.

On re-reading about the --directory option [0], I found that to add the
built-in default info directories, I just had to put this line:

export INFOPATH="$INFOPATH:"

...after running the Guix profile. This works for both the stand-alone
info and Emacs info.

Thanks for the help!
