Subject: Fix #2300: Default to current week.
X-Git-Tag: 2.16.0~17^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=20c140a2be1173899b08344188073eddfb83912f;p=thirdparty%2Fmoment.git

Fix #2300: Default to current week.

This update to Brian Schemp's patch calculates the current week once
instead of twice for a small performance boost.
