The msvc docs says that limit for the command line is 32,767 characters,
while ok for me, I think if not it would be better to check this limit?

Well, it's ARG_MAX in POSIX, and ARG_MAX is defined as 256K in Darwin, 512K in FreeBSD, 128K in Linux; _POSIX_ARG_MAX is defined as 4096 on all three platforms. Windows may differ too. Anyways, allocating even 128K in precious stack space is too much, that's why I suggest to use psprintf(). As for checking any hard limit, I don't think it would have much value - somehow we got the original command line, thus it is supported by the system, so we can just pass it on.
