Odd messages numbers

Looking at http://mdk.jack.kiev.ua/stats/gui/trunk/team/ we can see
that the "standard" number of messages to be translated is 13678.
But some teams have an odd number of messages. Eg Basque 11933,
Norwegian Bookmal 13683, ...etc.

Italian team had the same problem until few days ago. I corrected it running
 msgmerge -U my-lang.po file.pot
for each package needing to be corrected.

Is it possible to run a script doing this job for all teams in SVN?

Otherwise, i suggest all teams to do it by themselves.
It takes few minutes.
