I can point you to at least one similiar case in which the supposed fix did
fix the symptom but not the cause. The patch in question fixed the subshell
behaviour only when bash was used. With tcsh the same fix caused MC to hang.
I was able to predict that the patch is not good by just reading the patch.

I want to understand the problem or at least ot see a plausible explanation
as to what's causing it. If it is more than a short write I don't want your
patch to hide the real cause. Otherwise your patch is OK.
