send-email: find body-encoding correctly
In 8291db6f (git-send-email: add charset header if we add encoded 'From', 2007-11-16), "$1" is used from a regexp without using () to capture anything in $1. Later, when that value was used, it causes a warning about a variable being undefined, instead of using the correct value for comparison (not that it makes difference in the current code that does not do actual re-encoding).
