input: Only commit transactions when necessary

Browse source 
There is no need to check for transactions at the end of every user
input, as the vast majority of input will not issue transactions. This
implementation can also hide where changes are made without an
appropriate transaction commit, as a future unrelated input would issue
the commit instead.

Instead, commit transactions in places where changes are made or are
likely to be made.
