Thanks for the patch!

I pushed it as 3ddece896fddc38a29ab7e69f7c74f35e5a381fb with the
following changes:

I changed the source to fetch from Git. This type of tarball, which is
named "Source code (tar.gz)" on the web site, is generated automatically
by GitHub. These auto-generated tarballs actually change over time, as
GitHub updates their software. So, we fetch from Git in this case, to
ensure that package source will always be bit-identical.

`guix lint kirc` complained that the synopsis starts with an "article",
that is, with "A [...]". So I removed it.

And I removed what I consider "marketing language" from the synopsis and
description, and suggested in our manual's Synopses and Descriptions
section:

https://guix.gnu.org/manual/en/html_node/Synopses-and-Descriptions.html#Synopses-and-Descriptions

For example, the word "tiny" is subjective, and I think all programs
designed to be "usable" :)

Finally, I made sure to import the module (guix utils) in (gnu packages
irc). Otherwise, the package fails to build, like this:

------
ice-9/eval.scm:142:16: In procedure compile-top-call:
error: cc-for-target: unbound variable
hint: Did you forget `(use-modules (guix utils))'?
------

We request that you lint your packages and try building them before
submitting your patches. If you don't know how to do that, that's okay!
Just say so in the patch submission, and we will be happy to help.
