post guix pull shell command

[Andy Tai]

Hi, after doing a guix pull && guix package -u

this message is shown

hint: Consider setting the necessary environment variables by running:

     GUIX_PROFILE="/home/atai/.guix-profile"
     . "$GUIX_PROFILE/etc/profile"

I believe this actually means to ask the user to do

GUIX_PROFILE="/home/atai/.guix-profile"   . "$GUIX_PROFILE/etc/profile"


and if this is true, I would recommend to print the message as

hint: Consider setting the necessary environment variables by running:

     GUIX_PROFILE="/home/atai/.guix-profile"  \
     . "$GUIX_PROFILE/etc/profile"


to make it easy for the user to just copy and to paste that command line as it.
Thanks

This is correct as is.

You set the GUIX_PROFILE variable in the first command and then 
you source a file referencing the variable.

You cannot do this in one go, because $GUIX_PROFILE would evaluate 
to the empty string as the command has not been run yet.
