Sort filenames in .po translation files

[dhalbert]

xgettext --add-location=file does not sort the filenames: they seem to be in random order, which causes unnecessary diffs. We could post-process the files to sort the filenames.

I looked in the gettext bug list and don't see this mentioned in any open or closed bug.

Any chance this is just because we just pipe the output of find directly to xargs xgettext and find returns files in an arbitrary order? Perhaps piping through sort in the middle would do it.

It's worth a shot!

I was going to write an awk script or similar, but then discovered that the filenames could be split over multiple lines.

[tannewt]

I'm doing this. I think @godlygeek is right.

Either that, or use a static PYTHONHASHSEED.

@smurfix How does PYTHONHASHSEED fit into it?
