True.  If wine sees the effect of a quote the shell has removed (spaces
in an argument), it will quote the string with \", because if it
doesn't, the C runtime will parse the spaces:

[whit at giftie cmdl]$ wine cmdl.exe "quoted string"
arg 0: /cmdl.exe/
arg 1: /quoted string/
[whit at giftie cmdl]$ wine cmdl.exe \"quoted string\"
arg 0: /cmdl.exe/
arg 1: /"quoted/
arg 2: /string"/
[whit at giftie cmdl]$ wine --dll msvcrt=n cmdl.exe "quoted string"
arg 0: /cmdl.exe/
arg 1: /quoted string/
[whit at giftie cmdl]$ wine --dll msvcrt=n cmdl.exe \"quoted string\"
arg 0: /cmdl.exe/
arg 1: /"quoted/
arg 2: /string"/
[whit at giftie cmdl]$

I know, in my example, it is actually the unix shell that is breaking
the argument in half, but I am confident the windows C runtime startup
routines do the same.  Unlike the unix shell, they only preserve spaces
in an argument quoted by \", and treat " as an ordinary character.
Just follow the URL earlier in this thread.  It is where I got the
program I compiled with lcc-win as cmdl.exe:

#include <stdio.h>
main(int argc, char **argv)
{
    int i;
    for (i = 0; i < argc; i++)
        printf("arg %d: /%s/\n", i, argv[i]);
}
