- Function {\em addcmd()} expects a pointer to an array of {\em char $*$}'s as
- first argument. This pointer may be {\em NULL}. The {\em argv}-like
- array is expanded to hold a reference to {\em string}.
-
- The reallocated array {\em cmd} is returned. The last field in the
- array is {\em NULL} to indicate the ending of the list.
-
- {\bf Note that} a reference to {\em string} itself is not added to the
- list: a duplicate is made.
