send-email: find body-encoding correctly

In 8291db6 (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).
