Option to always prefer the longer sequence

[jmcwilliams403]

I've noticed that a lot of sequences I'd want to program would happen to start with the same sub-sequence as things from xorg, causing it to prefer those sequences instead of the longer ones and then type those instead. I don't want to get rid of the xorg sequences though because they're also useful. I'd like to request a feature where the user could specify to always prefer the longest sequence out of sequences that start with the same sub-sequence, and then allow for early-exits to the shorter sequences with either <space> or <Return>
