Subject: [PATCH] regression in process_text_window()

original code:

     if (linestart && (*cp & 0x80) != 0) {
         g_putch(*cp);
         end_glyphout();
         linestart = FALSE;
     } else {
         (void) putchar(*cp);
     }

new code:

    if (linestart) {
        if (SYMHANDLING(H_UTF8)) {
            /* FIXME: what is actually in that line? is it the \GNNNNNNNN or UTF-8? */
            g_putch(*cp);
        } else if ((*cp & 0x80) != 0) {
            g_putch(*cp);
            end_glyphout();
        }
        linestart = FALSE;
    } else {
        (void) putchar(*cp);
    }

The new code didn't output a character if linestart was true and the character did
not have bit 0x80 set.

fixed code:

    if (linestart) {
        if (SYMHANDLING(H_UTF8)) {
            /* FIXME: what is actually in that line? is it the \GNNNNNNNN or UTF-8? */
            g_putch(*cp);
        } else if ((*cp & 0x80) != 0) {
            g_putch(*cp);
            end_glyphout();
        } else {
            (void) putchar(*cp);
        }
        linestart = FALSE;
    } else {
        (void) putchar(*cp);
    }
