[PATCH 0/2] "M-x guix-search-by-name" and "M-x guix-packages-by-name".

[Alex Kost]

I almost never use "M-x guix-search-by-name" because I need to know a
real name of a package, and I rarely use "M-x guix-search-by-regexp",
because along with names it also searches in synopses and descriptions
(by default).

But I often use another command that allows me to display packages with
names matching regexp.  For example, I use it when I want to look at
packages with names that contain 'xml' or 'emacs'.  I believe this is
exactly what most people would expect from "M-x guix-search-by-name".

So what about renaming 'guix-search-by-name' into
'guix-packages-by-name' and adding a real 'guix-search-by-name' command
that will search for regexp in package names?

So:

- "M-x guix-packages-by-name guile" will display only guile packages
  (different versions and outputs)

- "M-x guix-search-by-name guile" will display all packages with "guile"
  string in names (like "guile-charting" or "guile-sly").
