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