From 615a99c2c20782daae5de38854025e2d40d85f29 Mon Sep 17 00:00:00 2001 From: John MacFarlane Date: Sun, 14 Jan 2018 15:10:13 -0800 Subject: RST reader: add aligned environment when needed in math. rst2latex.py uses an align* environment for math in `.. math::` blocks, so this math may contain line breaks. If it does, we put the math in an `aligned` environment to simulate rst2latex.py's behavior.
