[PATCH] gcc-changelog: detect Co-Authored-By before ChangeLog entries

[Martin Liška]

Pushed to master. It handles e.g. commit 
f1a68574b1f8d2961d3a676dbcf0cc24b6368578:
    libstdc++: Define __cpp_lib_to_chars for C++20 [PR 100146]

    

    This defines the feature test macro when uselocale is available, because

    the floating-point std::from_chars support currently depends on that.
