[PATCH v22 0/9] Support translated long option names in getopt and argp

[Vivien Kraus]

Dear glibc developers,

The test suite is still green for this series (except for a few tests
that timeout on my slow machine), and I am still waiting for your
feedback.

I am sorry for the revision number (22 is huge). I recognize that I
sent updated series in circumstances where I should not have done that.
I will try and not do that in the future.

I understand that this series is a little long, and so it takes some
time to review it. How can I make it easier for you?

In this series, I put the least important patches last. If you think
they are not needed, I will remove them in the next round.

What do you think?

Best regards,

Vivien
