Incorrect indentation of math blocks containing \iff

[jordan-arenstein]

Issue
When using a math block containing \iff, indenting the block using the = motion results in an increase of the indentation level for the rest of the document.

minimal.tex

\documentclass{minimal}
\begin{document}
\begin{equation}
ab = 0 \iff a = 0 \text{ or } b = 0
\end{equation}
\end{document}

Commands/Input
From the minimal.tex, select the entire file, and indent using =, and the final two lines are incorrectly indented.

Observed Behaviour

\documentclass{minimal}
\begin{document}
\begin{equation}
	ab = 0 \iff a = 0 \text{ or } b = 0
	\end{equation}
	\end{document}

Expected Behaviour

\documentclass{minimal}
\begin{document}
\begin{equation}
	ab = 0 \iff a = 0 \text{ or } b = 0
\end{equation}
\end{document}

I found a fix from #1078. My bad!

Ah, you're the second that has made the same comment, so I think perhaps my suggested fix should be part of what I termed "sane defaults". I'm pushing that now. Thus, you and @clason no longer have to change the configs for this particular issue.

[jordan-arenstein]

Incredible! Thanks for pushing that out so quick!

[lervag]

No problem; thanks for the clear issue description and for looking for and finding previous related work!
