I'm not sure what exactly are BASH, ASH and SH environment variables for in mc_shell_recognize_path(). They are not defined by corresponding shells.

[d3m3t3r]

The statement "... Midnight Commander will spawn a concurrent copy of your shell (the one defined in the SHELL variable and if it is not defined, then the one in the /etc/passwd file) ..." is not correct as /etc/passwd (~ getpwuid()) is not used in mc_shell_init() to detect shell.
