commit c75bb30fc10bb68a087995ce7f4bf16fd8b0a4b0
Author: Mike Frysinger <vapier@gentoo.org>
Date:   Sun Feb 13 02:44:31 2022 -0500

    newlib: libc: reshuffle include order for the manual
    
    When migrating the manual to the top-level, the include order was
    sorted by name of the subdir.  But this changed the chapter order
    of the manual in the process.  Change the sorting back to match
    existing chapters and update the comments to explain.
