Hi Stefan,
  I don't really understand the way PO stuff is supposed to work,
but I often get the problem that my git tree gets changed during
an out of tree build, causing the po subdirectory to be
dirtied.

I think this is due to the rule:

$(PO_PATH)/%.po: $(PO_PATH)/messages.po
        $(call quiet-command, msgmerge -q $@ $< > $@.bak && mv $@.bak $@, "  GEN   $@")

in po/Makefile.

Why does that merge into $(PO_PATH)/%.po rather than %.po - i.e.
why to the source rather than to the build directory?

Dave
