++/* Mar 16, 2003 Manuel Novoa III (mjn3@codepoet.org)
++ *
++ * 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
++ *
++ * for which 'wc -c' should output '0'.
