Original submission:

I have a lot of different environments (Python, Java, Postgres and 
so on), and I source a config file when I want to change the 
environment; for example running "include svn" runs

. $HOME/lib/config/svn

that adds SVN directories to PATH, LD_LIBRARY_PATH and MANPATH. 
When I do this under Midnight Commander I have a minor problem with 
subshell (at least I think the problem is in the subshell). When I 
run a program in the mc command line (type "./a_script", press 
[Enter]) mc (subshell?) passes the modified env vars to the 
program. But if I just press [Enter] on the program mc passes an 
old environment as if I didn't source any config file; it seems 
after pressing [Enter] on a program mc passes its own original 
environment, not the subshell's environment. I think that's a bug; 
I'd like mc to pass the modified environment to all programs 
regardless of the way I start them.

Debian GNU/Linux 3.1, mc 4.6.1-pre3.

It's already been fixed in the 2008-08-28 version of mc shipped with Slackware Linux 12.2. However, running a program using Alt-! still uses the old environment.

Replying to guanx:

running a program using Alt-! still uses the old environment.

that's because the filter is not run through the subshell.
i'm not sure that should be considered a bug as such, but see #3141.
