Pushing a huge nls commit

[Julien Lepiller]

Hi Guix!

Since last release, there have been some changes to the strings in guix and the 
manual. Our switch to weblate allows for a rolling translation workflow, so 
there have been significant changes to the translations.

I'd like to run "make download-po" on a more or less regular basis (maybe once 
a month?). However, the commits cannot be easily reviewed or split really well. 
This morning, I tried and got a commit:

52 files changed, 191755 insertions (+), 165535 deletions (-)

Note that weblate automatically updates the msgids in the po files, so most of 
the changes are actually in the English sentences, not in the translations 
themselves.

Is it ok to push such a big change to master after checking it doesn't break 
anything? How regularly should that happen?
