Subject: Fixed ellipsis support.
X-Git-Tag: 0.7.4~11
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=3ebbfbcb0cbd3df889ea867537126e5988db4869;p=njs.git

Fixed ellipsis support.

As of now, ellispis syntax is supported for function declaration with
the rest arguments.

This closes #365 issue on Github.
