Yes it was intended. Strsplit interfaces to the strtok() C routine,
char *strtok(char *s, const char *delim);
DESCRIPTION
A `token' is a nonempty string of characters not occurring
in the string delim, followed by \0 or by a character
occurring in delim.
and `split' gets passed as `delim'. The documentation is bad, though.
