[PATCH v3 6/7] send-email: suppress leading and trailing whitespaces in addresses

Remove leading and trailing whitespaces when sanitizing addresses so
that git send-email give the same output when passing arguments like
" jdoe@example.com   " or "\t jdoe@example.com " as with
"jdoe@example.com".

The next commit will introduce a test for this aswell.
