Interesting... the 7.0.99 version that I have doesn't have anything that
you are pointing to, and the example clearly used map <expr>. The
documentation was probably updated later on? What patch version do you
have? Or may be that I updated the vim binaries, not runtime, so I might
not be seeing the updates to documentation.
