Thanks for fixing these typos! What would you think about these being changed so that the error messages are written as ">=" instead of the more obscure "ge"? (I realize that you just followed the existing pattern here, so that's not a critique of your changes!)

Feel free to change it to whatever you prefer. I was only using "ge" to match what was done elsewhere.
