Fix notepad /p

[Francois Gouget]

The wine.inf defines the shell\print action as 'notepad /p %1' but 
notepad did not recognize '/' as the start of an option!

Another oddity I noticed is lots of things like:

    while (*cmdline && *cmdline == ' ') cmdline++;

Obviously if *cmdline==' ' then it's not going to be '\0'!
So I also simplified these.

Finally '/p' seemed to be pretty simple to implement so I gave it a try. 
At least it works for me.


Changelog:

  * programs/notepad/main.c

    Francois Gouget <fgouget at codeweavers.com>
    Also recognize '/' as the start of an option.
    Implement 'notepad /p'.
    Simplify many string parsing loops.
