[pelzflorian (Florian Pelz)]

Wow, thank you Antoine and Ludo!  This is well thought out.  Very nice!
Some comments though:

The commit message is missing the info that this patch also contains the
changes to doc/guix.texi and also to tests/guix-locate.sh.

This should be --database not --datebase.

The sentence does not end with a period.

I went on to test some things.  They are not very important, but still
there are bugs:

After deleting ~/.cache/guix/locate and cd’ing out of my home directory,
then inside “guix shell -CW coreutils”, “guix locate ls” does not find
ls.

When I use “guix locate icecat”, it legitimately also locates a file
lib/icecat/icecat in addition to the desired bin/icecat.  I try to
filter by “guix locate bin/icecat” or “guix locate -g bin/icecat”, but
it seems locate does not support file names with slashes.

Also, “guix locate” crashed for me on a machine where I was using the
nonfree channel to get support for my GPU and not just software
rendering.  “guix locate” crashed; it failed to load its module (nongnu
packages ncurses).  Sadly, after playing around without the bad channel,
I cannot replicate this anymore with the bad channel.  locate works now.
Strange.  And I cannot currently test on another machine for unrelated
reasons.
