Input messages not always split at message boundry

[ashermorgan]

Occasionally, the input module fails to parse messages when they are split in the middle. However, this does not seem to happen frequently enough to have any noticeable effect on gameplay.

(These errors do all come from the Input module, the [Sidecar] prefix is a typo).
