I don't know, but possibly? I don't think it really matters where it can appear though, since its behaviour can be impacted by the new option (see the code around line 102 in llvm-cxxfilt.cpp in this PR, where you've modified it - in particular, I'm interested in testing the behaviour of `Prefix` in combination with the quoting).
