Indeed. My bad. Does the following look like a good indentation style for shorter messages?

	if (lstat(path, &st) < 0) {
		if (err)
			strbuf_addf(err, _("could not stat HEAD at '%s'"), path);
		return -1;
          }

... and this for messages that are a bit longer:

	if (len == -1 && err)
		strbuf_addf(err, _("could not read the symlink HEAD at '%s'"),
			    path);
	else if (err)
		strbuf_addf(err, _("HEAD is a symlink ('%s') but target lives"
				   " outside refs/"), path);

resend if it doesn't. Excuse the noise in advance.
