Yes, it should.

It's the only shell (AFAIK) where we can use
  var+=value

that enables building a long list in a shell variable without quadratic
scaling.  You will notice this when using libtool with large code bases
(many object files or many deplibs).

Which is fine.  Please note that nontrivial additions need copyright
assignments (more off-list).

Not to XSI though.

I know w32 shells' properties are technically irrelevant.
For maintainer's sanity, these things are not irrelevant, though.
