py3: add r'' prefix to prevent b'' being prepended

The keys of keyword arguments should be str.

# skip-blame because we are adding just r'' prefixes.

     List changes in files, showing the revision id responsible for each line.
 
     This command is useful for discovering when a change was made and by whom.
 
     By default this command prints revision numbers. If you include --file,
     --user, or --date, the revision number is suppressed unless you also
     include --number. The default format can also be customized by setting
     fastannotate.defaultformat.

         This command uses an implementation different from the vanilla annotate
         command, which may produce slightly different (while still reasonable)
         outputs for some cases.
 
         Unlike the vanilla anootate, fastannotate follows rename regardless of
         the existence of --file.
 
         For the best performance when running on a full repo, use -c, -l,
         avoid -u, -d, -n. Use --linear and --no-content to make it even faster.
 
         For the best performance when running on a shallow (remotefilelog)
         repo, avoid --linear, --no-follow, or any diff options. As the server
         won't be able to populate annotate cache when non-default options
         affecting results are used.
