This recursive Git clone brings brings two libraries with it, 'tgl' and
'tl-parser':

https://github.com/majn/tgl/
https://github.com/vysheng/tl-parser

Is it possible to include these as their own separate Guix packages?
Would anything else potentially use them?

In general we try to avoid bundling things, but sometimes the effort is
not worth it.

If there are no tests, please add a comment like "No test suite". Or
else leave a comment explaining why we skip the tests.

Can you add a brief comment explaining this?

To make it a complete sentence, how about ""Telegram-purple is a Libpurple
protocol plugin that adds support for the Telegram messenger."?
