[Maxima] Question to Maxima Programmers

I just checked, and on my systems (both Windows and Linux), in both 5.15.0
and the current CVS version, Maxima behaves as it did before:
(%i1) 10;20;
(%o1) 10
(%o2) 20
(%i3)
I.e., (%i2) is not printed.

Subject: [Maxima] Question to Maxima Programmers
Dear Maxima programmers,
I have incorporated Maxima into my program Euler some time ago, and am very
happy with this combination of MatLab like computation and symbolic algebra.
However, with 5.15.0 I got a severe problem I cannot solve.
I am using pipes to speak to Maxima and get the results. This works well,
besides the problem that I am doing hard to determine the end of a Maxima
computation. Maxima sometimes sends its output in two chunks, so I cannot
simply wait until no character is available in the input line.
Until now, I used the input prompt to determine the end of the output.
However, in Version 5.15.0 Maxima sends this prompt even between multiple
commands in a line. So, sending "10; 20;" will return the two prompts. The
Maxima output looks like:
(%o1) 10
(%i2) (%o2) 20
(%i3)
Sometimes it stops after (%i2) and sends the rest in a separate chunk.
Before, the Maxima output was
(%o1) 10
(%o2) 20
(%i3)
So, I am stuck here, since I can no longer determine the end of the Maxima
output, unless I analyze the input myself and count the commands (a
nuisance, which might even not work).
Has anyone an idea how to solve this?
