i know, but i'm using my own function (for historical reasons):

mc ()
{
    local tf=$(mktemp);
    /usr/local/bin/mc -P $tf "$@" && test -r $tf && cd "$(<$tf)";
    rm -f $tf
}

... which, *cannot* have ever worked. it's somewhat unsurprising that i 
didn't notice, as my kde-based workflows don't rely on it working.

still, it seemed beizarre that i did't notice for a whole two decades,
so i looked around ... and each of my two other machines has a different 
working version: one has tf=/tmp/mc-`whoami`/wd$$, which i presume is 
the oldest one, and one has tf=$XDG_RUNTIME_DIR/mc-wd-$$. so i suppose 
i'm sleepwalking.  :'-D

dunno. but it would be a mediocre idea anyway, and absolutely terrible 
without the O_EXCL (because symlink attacks).

but anyway, this is an entirely self-made problem. sorry for the noise.
