mc subshell support

[balanga]

According to installation info:

Midnight Commander was built with subshell support, which works with most
popular shells, e.g. bash(1), dash(1), tcsh(1), zsh(1), but not sh(1) due
to its lack of "precmd" or equivalent hooks which mc(1) needs to read the
subshell's current directory.

Does this actually apply to tcsh?

It works fine with csh
if you need to use it with sh then you can start it with mc -u

It works with tcsh(1)/csh(1) (it's the same thing actually). Although mc(1) does mess up its history.

Well to prevent messing up history I have this (conditional on mc being installed on the system and only in interactive mode):

if ($?MC_SID) then
    unset savehist
    alias exit "echo 'You are in a Midnight Commander sub-shell, no way out'"
endif

This works for normal users, not for root, well, sometimes yes and sometimes no.

Via ports you can also have MC without subshell support; On computers where I cannot use ports I set an alias for "mc" → "mc -u" and "mcedit" → "mcedit -u".

I've gotten used to it. And I typically use tcsh(1)'s history-search-backward, so it's not that big of a deal.

I never use the sub-shell in mc but the history still gets dirty, so I disable it. And I only use tcsh
