Thanks to both of you for precisions about your point of view. Having thought more about it, it seems indeed strane to *interpret* log file content to *execute* script snippet in order to change window title or alike, following the link Kurt provided. It seems that old-fahion habits have taken advantage of backward-compatible features in modern emulated terminals.
Switching to the fa that emulator vendors should correct this, who to contact for it? I suppose it has nothing to do with the kernel, but rather with multiple GNU libraries around it. --- *B.
