This patch follows the suggestion Jakub made in the PR and is very straightforward.
With the patch, an abort is given on actual errors, in agreement with the
documentation for -dH.
(Yes, not very useful, but we can clear this PR)
Buffered errors bypass this abort by saving and restoring the state.
Regression tested on x86-64-linux.
OK for trunk and then back port to 5 in about a week?
A test case will be included, similar to that given by Dominique in the PR.
Regards,
Jerry

Restore the state before leaving.

The patch is simple enough. I will commit to trunk shortly if I hear from no one.
