| Are "&&" and "||" arithmetic expressions or ones of more general kind?
The ones in question are arithmetic (inside an $(( )) expansion.)
The "command line" || and && operate exactly as you described, and no-one
is planning to (or ever would) change that.
In my initial message, what was "odd" was not lazy eval of && and ||,
that's been around forever, but that it would be implemented that way
in ash (and remain in NetBSD's sh) in an environment when it is supposed
to be copying C expressions (so much so that the posix shell definition of
expressions in $(( )) just says "the same as this..." and points at the C
std, "except for no need for" ++, --, sizeof (and C statements, if/while/switch
etc).
