+ * 1) In handling '\c' escape, the previous version only suppressed the

+ * 2) SUSv3 specifies that octal escapes are of the form \0{#{#{#}}}.

+ * 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

+ * While fwrite(), fputc(), fputs(), etc. all set the stream error flag
+ * on failure, the *printf functions are unique in that they can fail
+ * for reasons not related to the actual output itself.  Among the possible
+ * reasons for failure which don't set the streams error indicator,
+ * SUSv3 lists EILSEQ, EINVAL, and ENOMEM.
+ *
+ * In some cases, it would be desireable to have a group of *printf()
+ * functions available that _always_ set the stream error indicator on
+ * failure.  That would allow us to defer error checking until applet
+ * exit.  Unfortunately, there is no standard way of setting a streams
+ * error indicator... even though we can clear it with clearerr().
+ *
+ * Therefore, we have to resort to implementation dependent code.  Feel
+ * free to send patches for stdio implementations where the following
+ * fails.
+ *
+ * NOTE: None of this is threadsafe.  As busybox is a nonthreaded app,
+ *       that isn't currently an issue.
