    exclude hidden files by default
    
    This emulates the behaviour of most globbing mechanisms: Hidden files,
    which start with a dot, are only captured when the pattern also
    explicitly states this dot. Most notably, this avoids duplication of any
    .git directory, which may take up significant space even for small,
    long-lived project. Its duplication may thus take long and is completely
    unnecessary to build.
