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