  /* Help to copy the thing properly quoted for the shell safety.
   * any single quote is replaced with '\'', any exclamation point
   * is replaced with '\!', and the whole thing is enclosed in a
   * single quote pair.
   *
   * For example, if you are passing the result to system() as an
   * argument:
   *
   * sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1))
   *
   * would be appropriate.  If the system() is going to call ssh to
   * run the command on the other side:
   *
   * sprintf(cmd, "git-diff-tree %s %s", sq_quote(arg0), sq_quote(arg1));

   * sprintf(rcmd, "ssh %s %s", sq_util/quote.host), sq_quote(cmd));

   *
   * Note that the above examples leak memory!  Remember to free result from
   * sq_quote() in a real application.
