Translation missing

Hello,

When I run the help for logstash (logstash 2.2.0) i notice a few parameters have translation missing. Was hoping for an opinion on the matter.

-w, --pipeline-workers COUNT  translation missing: en.logstash.runner.flag.pipeline-workers (default: 24)
-b, --pipeline-batch-size SIZE translation missing: en.logstash.runner.flag.pipeline-batch-size (default: 125)
-u, --pipeline-batch-delay DELAY_IN_MS translation missing: en.logstash.runner.flag.pipeline-batch-delay (default: 5)

root@db-core02:/etc/logstash/conf.d$ /opt/logstash/bin/logstash -h
Usage:
    /bin/logstash agent [OPTIONS]

Options:
    -f, --config CONFIG_PATH      Load the logstash config from a specific file
                                  or directory.  If a directory is given, all
                                  files in that directory will be concatenated
                                  in lexicographical order and then parsed as a
                                  single config file. You can also specify
                                  wildcards (globs) and any matched files will
                                  be loaded in the order described above.
    -e CONFIG_STRING              Use the given string as the configuration
                                  data. Same syntax as the config file. If no
                                  input is specified, then the following is
                                  used as the default input:
                                  "input { stdin { type => stdin } }"
                                  and if no output is specified, then the
                                  following is used as the default output:
                                  "output { stdout { codec => rubydebug } }"
                                  If you wish to use both defaults, please use
                                  the empty string for the '-e' flag.
                                   (default: "")
    -w, --pipeline-workers COUNT  translation missing: en.logstash.runner.flag.pipeline-workers (default: 24)
    -b, --pipeline-batch-size SIZE translation missing: en.logstash.runner.flag.pipeline-batch-size (default: 125)
    -u, --pipeline-batch-delay DELAY_IN_MS translation missing: en.logstash.runner.flag.pipeline-batch-delay (default: 5)
    -l, --log FILE                Write logstash internal logs to the given
                                  file. Without this flag, logstash will emit
                                  logs to standard output.
    -v                            Increase verbosity of logstash internal logs.
                                  Specifying once will show 'informational'
                                  logs. Specifying twice will show 'debug'
                                  logs. This flag is deprecated. You should use
                                  --verbose or --debug instead.
    --quiet                       Quieter logstash logging. This causes only 
                                  errors to be emitted.
    --verbose                     More verbose logging. This causes 'info' 
                                  level logs to be emitted.
    --debug                       Most verbose logging. This causes 'debug'
                                  level logs to be emitted.
    -V, --version                 Emit the version of logstash and its friends,
                                  then exit.
    -p, --pluginpath PATH         A path of where to find plugins. This flag
                                  can be given multiple times to include
                                  multiple paths. Plugins are expected to be
                                  in a specific directory hierarchy:
                                  'PATH/logstash/TYPE/NAME.rb' where TYPE is
                                  'inputs' 'filters', 'outputs' or 'codecs'
                                  and NAME is the name of the plugin.
    -t, --configtest              Check configuration for valid syntax and then exit.
    --[no-]allow-unsafe-shutdown  Force logstash to exit during shutdown even
                                  if there are still inflight events in memory.
                                  By default, logstash will refuse to quit until all
                                  received events have been pushed to the outputs.
                                   (default: false)
    -h, --help                    print help
