zsh-5.2-test-2

[Peter Stephenson <p.w.stephenson@xxxxxxxxxxxx>]

You can now find a second test version prior to zsh 5.3 in

http://www.zsh.org/pub/development/

Fixes since the first test version include those for the
following issues:

- the problem with "~-"

- a regression since 5.2 in use of ERR_EXIT / ERR_RETURN with shell
structures

- test failures owing to an environmental issue in an interactive test

It looks like I ought to be able to make a release at the weekend ---
note that at this stage it will not be held up by problems that were
already in 5.2.
