   6/* Help to copy the thing properly quoted for the shell safety.
   7 * any single quote is replaced with '\'', and the whole thing
   8 * is enclosed in a single quote pair.
   9 *
  10 * For example, if you are passing the result to system() as an
  11 * argument:
  12 *
  13 * sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1))
  14 *
  15 * would be appropriate.  If the system() is going to call ssh to
  16 * run the command on the other side:
  17 *
  18 * sprintf(cmd, "git-diff-tree %s %s", sq_quote(arg0), sq_quote(arg1));
  19 * sprintf(rcmd, "ssh %s %s", sq_quote(host), sq_quote(cmd));
  20 *
  21 * Note that the above examples leak memory!  Remember to free result from
  22 * sq_quote() in a real application.
