ms_deflate will return MSCOMP_ARG_ERROR when the in field is NULL, even when in_avail == 0.
I do this in Squash a lot when calling it with MSCOMP_FINISH or MSCOMP_FLUSH and I don't have any more data. Getting around it now by passing a pointer to a uint8_t on the stack (still with 0 for in_avail) and ms-compress is fine with it.
