Documentation issue with default value of padding argument of pad_sequences

[mhviraf]

I am not sure if this is the right place to open the issue since the issue is with Keras docs which is in the main repository but it is related to the preprocessing. Anyway, in the documentation under pad_sequences at https://keras.io/preprocessing/sequence/ the default value of padding is 'pre' however, a few lines below it, it says "Sequences that are shorter than num_timesteps are padded with value at the end."
