Summary: command line adds an extra space

Initial Comment:

I've noticed that the msys runtime will often add at least a trailing space (if more than one trailing space exists on the commandline, we can expect that it is expanded back to 1)

Simple test case:
== BOF test1.c ==
#include <stdio.h>
#include <windows.h>

int APIENTRY
WinMain (HINSTANCE hinstance,
   HINSTANCE hPrevInstance,
   LPSTR     lpCmdLine,
   int       nCmdShow)
{
   printf("lpCmdLine (%d) = **%s**\n", strlen(lpCmdLine), lpCmdLine);
   // strip right trailing spaces
   CHAR* cstrip = lpCmdLine + strlen(lpCmdLine) - 1;
   while (*cstrip == ' ')
     *cstrip-- = 0;
   printf("stripped (%d) = **%s**\n\n", strlen(lpCmdLine), lpCmdLine);
   return 0;
}
== EOF test1.c ==

With the folowing commands (please note that spaces are  important)
julienlecomte@PUMILIO ~
$ ./test1.exe "toto1"
lpCmdLine (6) = **toto1 **
stripped (5) = **toto1**
$ ./test1.exe toto3&& ./test1.exe toto4
lpCmdLine (6) = **toto3 **
stripped (5) = **toto3**
