LYNX-DEV latest development code: linux alpha sigsegv - token fix

[uid no body]

I got a sigsev, and tracked it to strtok call.  Apparently if strtok
returns NULL, it should not be called again on linux-alpha.  The fix is
near 6440 of src/HTML.c by inserting the "if( cp )":

            cp = strtok(me->textarea.data, "\n");
            LYUnEscapeEntities(cp, me->UsePlainSpace, me->HiddenValue);
            for (i = 0; i < me->textarea_rows; i++) {
                I.value = cp;

                chars = HText_beginInput(me->text, me->inUnderline, &I);
                for (; chars > 0; chars--)
                    HTML_put_character(me, '_');
                HText_appendCharacter(me->text, '\r');

if( cp )
                cp = strtok(NULL, "\n");
                LYUnEscapeEntities(cp, me->UsePlainSpace, me->HiddenValue);
            }
