This task is difficult and error prone when done manually, and this tool is there to help doing so correctly. You just need to provide the two versions of the POT file: before the edition and after as marked in the above synopsis, and it all becomes automatic.
make -C po/ update-po # for message program translations debconf-updatepo # for debconf translations po4a po4a.conf # for po4a based documentation translations
or something else, depending on your project's building settings. You know how to make sure your POT an PO files are uptodate, don't you??
cp myfile.pot myfile.pot.orig
mkdir po_fridge; cp *.po po_fridge
At this point, the typo fix fuzzied all the translations, and this unfortunate change is the only one between the PO files of your main directory and the one from the fridge. Here is how to solve this.
cp po_fridge/*.po .
msguntypot -o myfile.pot.orig -n myfile.pot *.po
rm -rf myfile.pot.orig po_fridge
You're done. The typo was eradicated from msgstr of both your POT and PO files, and the PO files were not fuzzyied in the process. Your translators love you already.
