657	New function: psStringSplit	Paul Price	David.Robbins@…	"This is sort of similar to Perl's split function.  I needed it for the pmFPA
functions, and figured that it would be generally useful so that we should
include it in psLib.

psList *psStringSplit(const char *string, const char *splitters);

\code{psStringSplit} shall split the input \code{string} into a
\code{psList} of \code{psStrings}.  The \code{string} is split at any
one of the characters in \code{splitters}.  Split strings of zero
length should not be included in the output list.


An implementation (also in psAdditionals.c in psModule branch pap_branch_051214):

// XXX: This should probably be implemented using strpbrk
psList *psStringSplit(const char *string,
                      const char *splitters)
{
    psList *values = psListAlloc(NULL); // The list of values to return
    unsigned int length = strlen(string); // The length of the string
    unsigned int numSplitters = strlen(splitters); // Number of characters that
might split
    unsigned int start = 0;             // The position of the start of a word
    for (int i = 1; i < length; i++) {
        bool split = false;             // Is this character a splitter?
        for (int j = 0; j < numSplitters && ! split; j++) {
            if (string[i] == splitters[j]) {
                split = true;
            }
        }
        if (split) {
            if (i == start) {
                // Some idiot put in two spaces, or two commas or something
                start++;
            } else {
                // We're at the end of the word
                psString word = psStringNCopy(&string[start], i - start);
                (void)psListAdd(values, PS_LIST_TAIL, word);
                start = i + 1;
                psFree(word);
            }
        }
    }
    if (start < length) {
        // Copy the last word
        psString word = psStringNCopy(&string[start], length - start);
        (void)psListAdd(values, PS_LIST_TAIL, word);
        psFree(word);
    }

    return values;
