Something has changed in the spellcheck behaviour for inflections.
In the portuguese main page on the the sentences is:
Nós prometo ajudá-lo.
There was one error in Nós prometo (verb form agreement error) but the spelling in the sentence is correct.
Now ajudá-lo is marked with a spelling error.
This would be OK for verb forms that are not hiphenated, but this is not the case here.
Since I have updated the hunspell dictionaries recently, I wondered if this is related with that update, but this change is very recent (one week tops) and they work perfectly in LibreOffice and system wide Hunspell.
Notice that if you choose pt-MZ that uses the standard "Dicionários Natura", you find the same issue.
Since there were recent changes to the spellchecker mechanisms, can this bug be related?
I checked now my most recent change to the tokenizer, but the hiphens were no touched.
\u002A \u002B are escaped + and * respectively.
