Subject: Fix add-path capability encoding, the length was not correctly calculated
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=13c74c40774c4259f8a61626ec62e0be40cfa7f8;p=openbsd

Fix add-path capability encoding, the length was not correctly calculated
because it included two extra bytes (copy-paste error from graceful restart).
