Removing unused locals and making vars into vals.

According to "git diff" the difference from master to this
commit includes:

   Minus: 112 vals, 135 vars
    Plus: 165 vals, 2 vars

Assuming all the removed ones were vals, which is true from 10K feet,
it suggests I removed 80 unused vals and turned 133 vars into vals.
There are a few other -Xlint driven improvements bundled with this,
like putting double-parentheses around Some((x, y)) so it doesn't
trigger the "adapting argument list" warning.
