I'm not sure about 1.  I haven't checked but this behavior was there
probably forever and we don't have a smart filling for equations w/o
alignment.  Do we want to pass this to Emacs standard filling rules?

About 2., we're talking about these environments, right:

  ("equation*") ("gather") ("gather*")
  ("gathered") ("multline") ("multline*")

The reason I'm asking is I was also thinking about a third solution
which can be in the styles.  There, we can check if user has removed the
LaTeX standard environments from `LaTeX-indent-environment-list' and
then make a decision.  Essentially in amsmath.el:

  (when (or (assoc "equation" LaTeX-indent-environment-list)
            (assoc "displaymath" LaTeX-indent-environment-list))
   <add other environments to `LaTeX-indent-environment-list'>)

What do you think, does this make sense?

Best, Arash
