Good to know it, thanks.

Okay, I see it.
But this is a problem that we may need longer string than STR_TOKEN_SIZE in multi token case.
So what you think about adding new typedef cmdline_multi_string_t for this case?
For example:
#define STR_MULTI_TOKEN_SIZE 1024
typedef char cmdline_multi_string_t[STR_MULTI_TOKEN_SIZE];
