+ * Rewritten to fix a number of problems and do some size optimizations.
+ * Problems in the previous busybox implementation (besides bloat) included: 
+ *  1) broken 'wc -c' optimization (read note below)
+ *  2) broken handling of '-' args
+ *  3) no checking of ferror on EOF returns
+ *  4) isprint() wasn't considered when word counting.
+ *
+ * TODO:
+ *
+ * When locale support is enabled, count multibyte chars in the '-m' case.
+ *
+ * NOTES:
+ *
+ * The previous busybox wc attempted an optimization using stat for the
+ * case of counting chars only.  I omitted that because it was broken.
+ * It didn't take into account the possibility of input coming from a
+ * pipe, or input from a file with file pointer not at the beginning.
+ *
+ * To implement such a speed optimization correctly, not only do you
+ * need the size, but also the file position.  Note also that the
+ * file position may be past the end of file.  Consider the example
+ * (adapted from example in gnu wc.c)
+ *
+ *      echo hello > /tmp/testfile &&
+ *      (dd ibs=1k skip=1 count=0 &> /dev/null ; wc -c) < /tmp/testfile
