New Revision: 13128

Modified:
   trunk/subversion/svnversion/main.c
Log:
Make the default error message for svnversion shorter and add an option
'--help', which display a longer help message that was the default error
message.

* subversion/svnversion/main.c
(usage): Replace the error message with shorter one suggesting an option
  '--help'. Also remove an argument 'options', which is no longer used
  in the function.
(help): A new function to display the help message, which was the error
  message displayed by the function 'usage', to stdout.
(main): Add lines for a new option '--help'. Also remove 'options' from
  arguments of 'usage'.
