    Address 'unsafe' XR/Relint regexp linter warnings
    
    While these changes pacify the linter and should be improvements
    over the old regexps, they are user-facing and not 100% equivalent.
    
    - In magit-log-propertize-keywords, identify bracketed keywords as
      greedy stretches without any bracket, rather than non-greedy
      stretches without an opening bracket.  This might be faster.
    
    - Avoid optional prefix (group 1) matching the empty string in
      magit-release-tag-regexp; instead, make the prefix nil on
      non-match.  All existing uses handle "" and nil as equivalent.
