Changelog entry

[xsuchy]

I used a code from an example in README and used:

specfile.add_changelog_entry(
    f"convert license to SPDX",
    author='Miroslav Suchý',
    email='[email protected]',
    timestamp=datetime.now(),                                                                                                                                                                     
)

but this produces the following diff:

 %changelog
+* Thu Apr 04 20:52:02 UTC 2024 Miroslav Suchý <[email protected]> - 1.10-50
+convert license to SPDX
+
 * Tue Jan 23 2024 Fedora Release Engineering <[email protected]> - 1.10-50

Either it should produce:

* Thu Apr 04 20:52:02 UTC 2024 Miroslav Suchý <[email protected]> - 1.10-50
- convert license to SPDX

or the example should be:

specfile.add_changelog_entry(
    '- New upstream release 2.1',
