cppman std::ostream opens std::ostream_iterator?

[jep-dev]

I installed on Ubuntu 20.04 via apt-get. I noticed that man -k --regex '[Ss]ame' didn't find std::same_as or std::Same, while man std::Same worked. So there may be something weird about my installation. In any case man std::ostream work as expected, cppman std::ostream did not. The name is an exact match, but I assume some kind of fuzzy matching or completion went wrong. Can anyone reproduce this?

By the way, information on std::Same is very sparse, and now despite using double quotes, Google thinks I have STD's. In any case, the link is here and it claims to be C++20.
