In 'git log', the --decorate-refs-exclude option appends a pattern to a string_list. This list is used to prevent showing some refs in the decoration output, or even by --simplify-by-decoration. Users may want to use their refs space to store utility refs that should not appear in the decoration output. For example, Scalar [1] runs a background fetch but places the "new" refs inside the refs/scalar/hidden/<remote>/* refspace instead of refs/<remote>/* to avoid updating remote refs when the user is not looking. However, these "hidden" refs appear during regular 'git log' queries. A similar idea to use "hidden" refs is under consideration for core Git [2]. Add the 'log.excludeDecoration' config option so users can exclude some refs from decorations by default instead of needing to use --decorate-refs-exclude manually. The config value is multi-valued much like the command-line option. The documentation is careful to point out that the config value can be overridden by the --decorate-refs option, even though --decorate-refs-exclude would always "win" over --decorate-refs. Since the 'log.excludeDecoration' takes lower precedence to --decorate-refs, and --decorate-refs-exclude takes higher precedence, the struct decoration_filter needed another field. This led also to new logic in load_ref_decorations() and ref_filter_match(). There are several tests in t4202-log.sh that test the --decorate-refs-(include|exclude) options, so these are extended. Since the expected output is already stored as a file, most tests could simply replace a "--decorate-refs-exclude" option with an in-line config setting. Other tests involve the precedence of the config option compared to command-line options and needed more modification.
