• Honor XDG_DATA_HOME precedence for extension globs, so a glob entry
  from a higher-priority data dir overrides one from a lower-priority
  dir instead of being silently shadowed (#62, liujianqiang-niu).
  
• Fix open() precedence and stale filehandle bugs in
  File::MimeInfo::default and File::MimeInfo::Magic.
  
• Don't die when @ARGV contains bytes that are invalid in the current
  locale; decode leniently and continue.
  
• Refactor resolvelink to use Cwd::abs_path instead of a hand-rolled
  loop.
  
• mimetype/mimeopen: quote filenames in diagnostic output via
  B::cstring so unusual characters render unambiguously.
