man.fish can be clarified a bit, by removing a superfluous early return. Additionally, performance can be (ever so slightly) improved, by using the empty string to suffix an extra colon when `$MANPATH` is empty, as described in `manpath(1)`. As `man` will internally call `manpath` as it starts, this eliminates a redundancy.
