[bug #59795] interaction of .na and '.ad l' documented incorrectly

[G. Branden Robinson]

Follow-up Comment #11, bug #59795 (project groff):

[comment #10 comment #10:]
> It also smells a little funny to start right-adjusting if the adjustment
mode is out of range (that's what adjust_mode = 5 means).  I'll have to see if
AT&T troff supported numeric adjustment modes; it is already known that V7
troff did not support the .j register.

Sigh.

V7 /usr/src/cmd/troff/n5.c:


casead(){
        register i;

        ad = 1;
        /*leave admod alone*/
        if(skip())return;
        switch(i = getch() & CMASK){
                case 'r':       /*right adj, left ragged*/
                        admod = 2;
                        break;
                case 'l':       /*left adj, right ragged*/
                        admod = ad = 0; /*same as casena*/
                        break;
                case 'c':       /*centered adj*/
                        admod = 1;
                        break;
                case 'b': case 'n':
                        admod = 0;
                        break;
                case '0': case '2': case '4':
                        ad = 0;
                case '1': case '3': case '5':
                        admod = (i - '0')/2;
        }
}
casena(){
        ad = 0;
}
