So if I want to know what ideas are based on, I should refer to how
FBSD tcsh and sh behave and not how Bash on Linux functions? Or as far
as this type of thing is concerned, it would stay either way because
it was an original implementation decision? (obviously, because of the
former, the later becomes moot, but I'm curious what the current
mindset of development is)
