You are correct, --language-force doesn't help at all in filter mode. I should have known better since I was looking at strace output when debugging this. The general issue seems to be that different parsers may behave differently in this respect. Ultimately the parser should obey what it was told by gtags, so trimming the list would perhaps be the best option.
