When installing a package that needs an environment variaible to be set =
for
use, `guix install` prints e.g.:

$ guix install python
...
The following environment variable definitions may be needed:
   export =
PYTHONPATH=3D"/home/rob/.guix-profile/lib/python3.7/site-packages${PYTHONP=
ATH:+:}$PYTHONPATH"

I understand that the variable will be set in a new shell, but not in =
the current shell.
But as it stands, the message serves to confuse even users that are =
somewhat experienced
with unix-like systems.

Suggestion to instead print:

Set the following environment variables to use <package> right away:
   export =
PYTHONPATH=3D"/home/rob/.guix-profile/lib/python3.7/site-packages${PYTHONP=
ATH:+:}$PYTHONPATH"
