I agree with our comments, but this not solves the original issue with
windows (double backslash).

- we can't use '\' because it force to double it for windows
- we must be able to escape characters to be able to use ',' and '=' in
filename (in fact ' ' is not an issue).

perhaps the solution is to use a different escape character ?

Do you like '^' ?

qemu -hda "my file" -> filename is "my file"
qemu -hda my^,file -> filename is "my,file"
qemu -drive file=my^^file -> filename is "my^file"

Johannes, I'm sorry, but it seems there is no other way than reparsing
(lightly) the string.
