This makes me wonder when the `apropos` command was introduced; surely
the name was also somewhat of an obscure joke ("what is apropos of
listing a directory?" is not exactly the phrase that springs
immediately to mind when wondering how to list a directory).

Looks like it was introduced in 2BSD, written by Bill Joy, though the 4.4BSD manpage claims that it was introduced in 3BSD.  Neither the BSD source nor manpage are particularly enlightening about the choice of name.
