- seq_printf(seq, "%*s\n", 127 - len, ""); + seq_pad(seq, '\n');Hmm, seq_pad is unintuitive. I would say it pads the string by '\n'. Of course it does not, but...I don't think this is a very serious problem. Currently, the padding character is always ' ' for all existing callers, so it only makes sense to make the trailing character an argument.
If you want, we can rename seq_pad() to seq_pad_and_putc(). Also we can pass
both the padding character (e.g. ' ') and the trailing character (e.g. '\n')
like seq_pad_and_putc((' ' << 8) | '\n'), though I wonder someone wants to
use '\0', '\t', '\n' etc. as the padding character...
