I actually looked yesterday if I could make a PR for rpm implementing it
but I couldn't really find a good way to do it. So I decided to implement it
in `rpkg-client` (https://pagure.io/rpkg-client/branch/spec_preprocessor -
basically a hack upon python-rpkg library) by spec preprocessing. So,
with that development version of rpkg, you can have specs (or rather spec
templates) like this in your Git project:

Name:       {{{ git_name }}}
Version:    {{{ git_version }}}
Release:    1%{?dist}
Summary:    This is a test package.

License:    GPLv2+
URL:        https://someurl.org

Source: {{{ make_source }}}

%description
This is a test package.

%prep
{{{ setup }}}

{{{ git_change_log }}}

rpkg will take that spec template and replace the {{{ ... }}} tags with
standard output of the commands inside the braces (git_name, git_version,
make_source, setup, git_change_log are all shell functions). Afterwards,
the generated spec is used to e.g. create an srpm (done by `rpkg srpm`
command).

I haven't actually implemented the `git_change_log` function yet (nor the
other functions except for `make_source`) like Igor did - currently it just
always returns '%changelog' and that's it but I wanted to show this to
possibly get some feedback.

Thank you
