/* Help to copy the thing properly quoted for the shell safety.
* any single quote is replaced with '\'', and the whole thing
* is enclosed in a single quote pair.
* For example, if you are passing the result to system() as an
* argument:
* sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1))
* would be appropriate. If the system() is going to call ssh to
* 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_quote(host), sq_quote(cmd));
* Note that the above examples leak memory! Remember to free result from
* sq_quote() in a real application.
