Subject: Add missing test vector for anchors_zero_fee_htlc_tx
X-Git-Tag: v0.0.115~64^2~1
X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=3fe9aadd9d2045970ebe0702c03ce1980b544daa;p=rust-lightning

Add missing test vector for anchors_zero_fee_htlc_tx

Tests the case where only one anchor output exists for the funder in the
commitment transaction due to the remote having a dust balance (in this
case, 0).
