git-svn: check error code of send_txstream 

Not checking the error code of a function used to transform and
send data makes me nervous.  It currently returns "undef" on
success; so die if we get any result other than "undef" because
it's likely something went wrong somewhere.  I really wish this
function returned an MD5 like send_stream (or better yet, SHA1)
for verification.
