Yuck. :)

I would be tempted to do:

	static int strbuf_utf8_width(const struct strbuf *sb)
	{
		char char *p = sb->buf;
		size_t remainder = sb->len;
		int width;

		width = utf8_width(&p, &remainder);
		if (!p || remainder)
			return sb->len;
		return width;
	}
	...

		struct strbuf sb = STRBUF_INIT;
		const char *p;

		strbuf_addf(&sb, _("available %s in '%s'"), title, exec_path);
		fwrite(sb.buf, sb.len, 1, stdout);
		putchar('\n');

		/* NEEDSWORK: handle non-UTF8 locales? */
		mput_char('-', strbuf_utf8_width(&sb));

		strbuf_release(&sb);
