Merge branch '2742_ash'
* 2742_ash: revert changes related to BASH shell prompt Code refactoring Improve subshell chapter in online help Minor code changes. New subshell types Busybox ash + Debian ash (dash) and some more enhancements plus fish chdir bugfix Make MC's special commands not show up in bash's history and also suppress consecutive identical commands.
