case inversion in TeXmacs output

Hello,

I just noticed a case inversion problem with TeXmacs.

I'am using WinTeXmacs and Maxima-5.9.3 on Windows.

My session looks like this:

(%I1) 'foo;
(%O1) FOO
(%I2) 'Foo;
(%O2) Foo
(%I3) 'FOO;
(%O3) foo
(%I4) %O3;
(%O4) %o3
(%I5) %o3;
(%O5) foo

It seems there is a call to  maybe-invert-string-case (src/commac.lisp)  needed when 
passing Maxima output to TeXmacs. 

Is there anybody who can help?
