I mean the latter.  Here's what I have:


a oeu aoeu aoe uao ue oaeua ou oau oe uoo ue aoeu ao eua oue aoe uao aoue aoe uoa eu aoeu eoaauo
%
$$x=a$$
%
aoe eoaua oeu aoeu eoa eoa eoauoae uoae ueoa ueoa u ao euao eeoa eoaueoa ueoa ueoaueoa aoeu.


becomes


a oeu aoeu aoe uao ue oaeua ou oau oe uoo ue aoeu ao eua oue aoe uao
aoue aoe uoa eu aoeu eoaauo
%
$$x=a$$
%
aoe eoaua oeu aoeu eoa eoa eoauoae uoae ueoa ueoa u ao euao eeoa
eoaueoa ueoa ueoaueoa aoeu.


when I press M-q above and below displayed math.

However, when I try that on another computer with the same version of
Emacs and AUCTeX, I get this instead:


a oeu aoeu aoe uao ue oaeua ou oau oe uoo ue aoeu ao eua oue aoe uao
aoue aoe uoa eu aoeu eoaauo
%
$$x=a$$
% aoe eoaua oeu aoeu eoa eoa eoauoae uoae ueoa ueoa u ao euao eeoa
eoaueoa ueoa ueoaueoa aoeu.


Which is very strange because I don't see any differences in
TeX-related settings on the two installations (in particular, there
are no customizations of TeX-mode filling).
