I think that this should be considered to be a bug in Maxima.

The point is that, in mathematics, the big summation operator usually has a larger binding force than the addition.  This is the convention that allows you to write sum_i a_i + sum_i b_i.
In any case, this is what TeXmacs assumes.  Of course, the fact that the right-hand x_i depends on i suggests an other convention.  Still, I think that this is wrong.

I checked this on a large corpus of articles by mathematicians and I did not yet find a single paper that deviates from the standard (though implicit) convention.

This is TeXmacs SVN 14093M, with maxima 5.46, on FreeBSD.

I start a maxima session and input the line


Then I activate mathematical input mode, copy the output to the next input line, and hit return.  The result is


which is wrong.

I attach a .tm file and a .pdf version, which make the problem clearer.
