Builds a :tl`ReplyInlineMarkup` or :tl:`ReplyKeyboardMarkup` for
the given buttons, or does nothing if either no buttons are
provided or the provided argument is already a reply markup.
This will add any event handlers defined in the
buttons and delete old ones not to call them twice,
so you should probably call this method manually for
serious bots instead re-adding handlers every time you
send a message. Magic can only go so far.
