The code does this because every possible completion has a hyphen. If
muffle-warning was called muffle-the-warning all of them would have
two hyphens, and the completion would be 'mu--' (with the point placed
after 'u').

The documentation is obscure but correct I think. I had meant to cover
this case by putting the '^' in the regexp and not having a '$' at the
end, i.e. the regexp doesn't have to match to the end of the
string. The partial completion is then computed from the commonality
of the available completions, without reference to the input string.

That make sense?

(This is a pretty hard feature to document clearly. I'll see if there
is a good description to swipe from completer.el.)
