[PATCH 0/2] emacs: Use full profile name in Guix buffer names.

[Alex Kost]

Currently names of buffers with Guix packages may look mysterious.
If you call "M-x guix-installed-user-package", you get:

  *Guix Package List: guix-profile*

If you call "M-x guix-installed-system-packages", you get:

  *Guix Package List: profile*

It is not obvious what "guix-profile" and "profile" stand for.  The
answer is: it is just a last part of profile name:

  /var/guix/profiles/per-user/<user>/guix-profile → guix-profile
  /var/guix/profiles/system/profile               → profile

I think it will be more user-friendly if a default buffer name contains
a full profile name.  The result buffer name may be a bit long, but at
least it is clear, WDYT?

These patches do this change.  To return to the old style of buffer
names, one can use this setting:

  (setq guix-ui-buffer-name-function 'guix-ui-buffer-name-short)
