argv_split: allow argv_split to handle NULL pointer in argcp parameter gracefully
It would be nice if the argv_split library function could gracefully handle
a NULL pointer in the argcp parameter, so as to allow functions using it
that did not care about the value of argc to not have to declare a useless
variable. This patch accomplishes that. Tested by me, with successful
results.
