pg_standby (wrong parametr -u in help note

Hello

I found unsupported parametr -u in help to pg_standby:

Usage:
  pg_standby [OPTION]... [ARCHIVELOCATION] [NEXTWALFILE] [XLOGFILEPATH]
                                                  note space between
[ARCHIVELOCATION] and [NEXTWALFILE]
with main intended use via restore_command in the recovery.conf
         restore_command = 'pg_standby [OPTION]... [ARCHIVELOCATION] %f %p'
e.g. restore_command = 'pg_standby -l -u /mnt/server/archiverdir %f %p'


again:
pg_standby -l >>>>>-u<<<<<< /mnt/server/archiverdir %f %p'
