Hi, Sorry for that, it seems I had leave it partly commited in, without
a news entry and documentation.  The change about
/etc/skel/.bash_profile in commit 40310e is to provide a sensible
default to merge multiple profiles, which will fix
<https://issues.guix.gnu.org/20255>.  Users can easily change his own
~/.bash_profile to not invoke 'guix package', to avoid merge multiple
profiles.

Now I think it's better to remove it as the patch did, so we default to
not merge search paths from multiple profiles, and document how to
custom your ~/.bash_profile with 'guix package --search-paths` to merge
them.  Also mention the drawback when you choose to merge profiles for
search paths, mainly ABI incompatible problems from plugins (GIO
modules, Qt, etc.).

Thanks.
