small bugs in vncviewer 3.3.3r1

[Bruce Lilly]

Hi,

vncviewer -h (as distributed with SuSE 8.0 Intel) gives:

VNC viewer version 3.3.3r1 with SSH tunneling support

usage: vncviewer [<options>] [<host>:]<display#>
         vncviewer [<options>] -listen [<display#>]
         vncviewer [<options>] -tunnel <host>:<display#>

<options> are standard Xt options, or:
                -shared
                -viewonly
                -fullscreen
                -passwd <passwd-file>
                -encodings <encoding-list> (e.g. "raw copyrect")
                -bgr233
                -owncmap
                -truecolour
                -depth <depth>


The first usage line is incorrect, and should be:

usage: vncviewer [<options>] [<host>]:<display#>

i.e. the colon before the display number is NOT optional.
The same may apply to the -listen version.
And the -h flag should probably be self-documenting.

Best regards,
