I can't tell you "why" this happens, but it seems that "how" it happens is
that the "/man" is being appended to the result of the parameter expansion
before globbing takes place. Evidently, when the ~ is processed it sets a flag
which allows globbing to happen further down the line, rather than forcing
globbing to happen at that point.
