[PATCH][BZ 18934] hu_HU: Fix multiple sorting bugs.

[Egmont Koblinger]

Carlos, any news?

Did Luis's and my comment help you move forward?

I'd like to emphasize again that my patch does not do anythinig
serious. No big redesign, no fundamental change, nothing like this.
The things Luis mentioned were either already implemented that way, or
I did not touch them. It's just a few, technically small bugfixes that
I made. Really nothing big deal. Plus unittests.

I have, a long time ago, offered that I can turn this all-in-one patch
into like 4-5 patches to be applied on top of each other. But then
they'd have to be reviewed and applied in a particular order (because
they'd heavily conflict) at once. I know that generally this is the
preferred approach, however, it cannot work together with test driven
development since there's no way to test the intermediate (i.e.
deliberately still broken) states. Having chosen TDD, the result of my
work was a patch that fixes all the referred bugs in a single step. I
can, I still offer to spend some more time on it to create a few
smaller, easier to review patches *if* seriously that is what's
missing from getting my work accepted. Let me know.

cheers,
egmont
