[bug#69251] [PATCH] gnu: Add r-abbreviate.

[Skyler Ferris via Guix-patches via <guix-patches@gnu.org>]

Each section includes a checklist based on (and expands upon) the items 
listed in the manual (22.7 "Submitting Patches"). Each checklist item 
may have one of the following statuses:

C: Commitable. This item looks as expected for a final commit.
CC: Commitable with Context. Like commitable, but some notes have been 
added providing context about anything notable or unusual. These notes 
are provided for transparency and should not be interpreted as meaning 
that I object to the patch.
MR: Minor Repair. There is something about the patch which I think 
should ideally be changed, but I do not think that the patch should be 
refused on this basis alone.
A: Attention. Something in the patch needs attention from the author, 
the committer, or both. Resolving the matter may or may not require a 
change to the patch.
XX: This item is not relevant to the patch.
Blank: I did not review this aspect of the patch.

# Cryptographic Hash

I was not able to locate a cryptographic hash for this package.

# Project is Maintained

All of the commits are from the end of 2021 and the version remains at 
"0.1". However, the package is doing something relatively simple and 
there are no open issues on the GitHub page (to be fair, there is only 
one closed issue and it was handled ~2 months after the project was 
uploaded).

There were about 1000 downloads within the past month at time of writing 
(https://cranlogs.r-pkg.org/badges/last-month/abbreviate), implying that 
some number of people are using the package. Combined with the lack of 
issue reports, this gives some confidence that the lack of new commits 
is "this doesn't need any changes" rather than "this is unmaintained".

# guix lint

There is a note that the source is not archived on Software Heritage or 
Disarchive database. The 'archival' section in the "Invoking 'guix 
lint'" chapter (9.8) indicates that the Software Heritage will pick up 
the source at some point in the future.

# Works in container with minimal inputs

I used the following environment:

$ ./pre-inst-env guix shell -C r-abbreviate r
 > library(abbreviate)

Then I entered some of the example commands from the README. The calls 
were successful and produced reasonable-looking output.

# Simulated Guix Pull

I committed the diff locally and used `--disable-authentication`, which 
I think is fine because the signature on the commit is unrelated to the 
contents of the commit in this context.
