I use UNIX-like OSes for several years and still don't understand for
what reason people tend to combine two completely different shells:
interactive shell and command shell (/bin/sh). Why not to completely
seperate /bin/sh from the interactive shell, make it as small as
possible, make it statically linked (or at least without linking it
with libedit and libtermcap). Additional benefit for this is that such
a lighweight /bin/sh will be faster for configure-like things.
