If I understand you correctly, you want to make sure a certain file
that was committed to the repo a while ago vanishes without a trace.
If this is correct, then you could do a hg->hg conversion using the
convert extension with a mapping that excludes the file in question.
Note that this will change all cset hashes beyond the cset that
introduced the file.
