Re: style change: explicitly permit braces for single statements

        if (ch == t.c_cc[VINTR]) {
                ...do INTR processing...
        } else {
                if (ch == t.c_cc[VQUIT]) {
                        ...do QUIT processing...
                } else {
                        if (ch == t.c_cc[VKILL]) {
                                ...do KILL processing...
                        } else {
                                ...etc
                        }
                }
        }

For this, I would prefer

        if (ch == t.c_cc[VINTR]) {
                ...do INTR processing...
        } else if (ch == t.c_cc[VQUIT]) {
                ...do QUIT processing...
        } else if (ch == t.c_cc[VKILL]) {
                ...do KILL processing...
        } else {
                ...etc
        }

In this case, perhaps even a switch might better, assuming that all of 
the t_c.cc[] are unique:

        switch (ch) {
        case t.c_cc[VINTR]) {
                ...do INTR processing...
                break;
        };
        case t.c_cc[VQUIT]) {
                ...do QUIT processing...
                break;
        }
        case t.c_cc[VKILL]) {
                ...do KILL processing...
                break;
        }
        ...etc
