|  | * single quote pair. |

|  | * sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1)) |

|  | * 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 |
