For the changelog for documentation, I normally put the section in the
round brackets, then describe the change after the colon. So, I changed
this to:

* doc/guix.texi (origin Reference): Add documentation for hg-fetch.

hg-fetch accepts an optional name parameter, so I added that here since
the text refers to it. Assuming you copied the git-fetch documentation,
that's maybe deficient as it doesn't mention all the parameters.

There's a typo regarding git-reference here which I removed.
