   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.
