Subject: m.math: process all math in the directive at once.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~cjwatson/git?a=commitdiff_plain;h=6992402f372f7d5df12fa4f8080af4c90dd2bb7b;p=blog.git

m.math: process all math in the directive at once.

Having multiple blocks is not very useful, as you don't get any of the
fancy typesetting features for that. Use latex arrays for that or
put the math into multiple consecutive directives.
