borgmatic 1.7.11

• #479, #588: BREAKING: Automatically use the "archive_name_format" option to filter which archives
  get used for borgmatic actions that operate on multiple archives. Override this behavior with the
  new "match_archives" option in the storage section. This change is "breaking" in that it silently
  changes which archives get considered for "rlist", "prune", "check", etc. See the documentation
  for more information:

• #479, #588: The "prefix" options have been deprecated in favor of the new "archive_name_format"
  auto-matching behavior and the "match_archives" option.
• #658: Add "--log-file-format" flag for customizing the log message format. See the documentation
  for more information:

• #662: Fix regression in which the "check_repositories" option failed to match repositories.
• #663: Fix regression in which the "transfer" action produced a traceback.
• Add spellchecking of source code during test runs.
