mc subshell on FreeBSD

["Eugene M. Zheganin" <emz norma perm ru>]

Hi.

Why when I'm using a subshell with Ctrl-O on FreeBSD it's always
poisoned with a 'cd' commands from previous MC history of directory
entering (for example when I'm entering 'security' directory I got "cd
"`printf "%b" '\0057etc\0057security'`"" in shell history). When I'm
using MC and a subshell on Linux/Solaris this doesn't happen.

Is this a bug ?

Linux MC version is 4.8.4
FreeBSD version is 4.8.8
Solaris version is 4.7.5.2, but I don't think version has to do
something here.

Eugene.
