Actually, it is not as easy as it seems to be.
First of all, you can do "po4a -v fdim.3.cfg" several times, they will
always update the po file. The story is that it is not trivial to detect
when the po file should be updated and we decided to update them
inconditionally.
Here is an example of problem:
Imagine three times: day1 < day2 < day3
POT gets updated on day1 and day2
Translator works on day3, but based on pot of day1.
The po file must be updated against the day2 pot version, even if hte po
file itself is more recent.
Then, you could argue that we have to use the POT revision dates from the
header instead of trusting the file modification date, but it will not help
us much here. We rely on msgmerge to do the merge, with the -U flag to
update the po file. Unfortunately, the documentation says:
-U, --update
update def.po, do nothing if def.po already up to date
It does not even update the POT revision date of the po file (just tested).
So, in summary, I think that we should:
- use the POT revision date to decide whether we update the po file or not
- bug msgmerge for not updating this when the other fields do not change
or not rely on "msgmerge *-U*" here
