Thanks for raising this inconsistency.  My vote is to harmonize this and
add all math environments to `LaTeX-indent-environment-list',
i.e. disabling filling.  Then the question is how a user can control the
custom variable when we add entries to it as a style is loaded like in
your patch above?  For example, how can I decide here that "multline"
shouldn't be in that variable?  Or am I missing something?

Best, Arash
