Is this issue reproducible using the latest version of Midnight Commander?

• I confirm the issue is still reproducible with the latest version of Midnight Commander

How to reproduce

source mc.sh to set up using mc-wrapper.sh. This way, when quitting mc, the shell changes to that directory.

Go to a directory whose name ends in a newline. Quit mc. The shell doesn't change there.

Related to #2325 / pending PR #4804. Command substituion, used for reading the file's contents, strips off all trailing newlines.

A solution could be for the emitter to emit an additional letter, and then to strip it off using shell string operations:

MC_PWD="`cat "$MC_PWD_FILE"; echo _`"
MC_PWD="${MC_PWD%_}"
