Apparently sometime in the recent past, the ability to name folders with a comma went away. I know this seems superpicky, but we actually use commas separating information in folder names, and this is a real pain. We just noticed the other day, but I didn't bring it up until upgrading to Vault to 3.1.1, and the problem is in there. If you try to create a new folder in the Vault GUI, and at any point type a comma, it does nothing. I assume the comma was at some point considered an invalid character, which I think is a mistake.
