I should be pretty easy to just append the contents of multiple fies,
even inter-mingled with -m options.  We just do a callback like Johannes
just did for -m in builtin-commit.c for -F and append to the same
strbuf.  strbuf_read() already appends, so the callback could look
something like:

static int opt_parse_F(const struct option *opt, const char *arg, int
unset)
{
        struct strbuf *buf = opt->value;

	if (!strcmp(arg, "-")) {
                if (isatty(0))
                        fprintf(stderr, "(reading log message from
standard input)\n");
                if (strbuf_read(&sb, 0, 0) < 0)
                        die("could not read log from standard input");
	} else {
                if (strbuf_read_file(&sb, logfile, 0) < 0)
                        die("could not read log file '%s': %s",
                            logfile, strerror(errno));
	}
}

Shouldn't be too hard :)
