send-email: squelch warning due to comparing undefined $_ to ""

Browse Source 
The check to see if initial_reply_to is defined was also comparing $_ to
"" for a reason I cannot ascertain (looking at the commit which made the
change didn't provide enlightenment), but if $_ is undefined, perl
generates a warning.
