[PATCH] git-send-email: provide hook to send lines more than 998 symbols

By default git-send-email does not accept patch which is contain lines longer
than 998 symbols. Sometime it's inconvenient, i.e. you have a long list in one
variable in shell script. So, define environment variable
GIT_SEND_EMAIL_LONGLINE to something to avoid that restriction.
