Off-topic, but: yes! One of my big annoyances with autocorrect is it auto-uncorrecting "its" to "it's", "well" to "we'll", etc. Not sure what algorithm is used, but it seems to be fairly horrible (BTW - I'm on a Moto X now and used to have an iPhone; I've seen it in both).

The only way to do this would be to wait until enough of the sentence has been written to get context. Failing that, though...I just don't want it to touch those words at all.
