As for the inserting and listing of matches: the explicitly used
matching spec makes both names possible matches, so only they should
be used and shown (after all that's what all this matching stuff is
about).
As for the cursor position: I tried to make the completion code clever 
here by making it leave the cursor in the place where it is easiest to
make the inserted line unambiguous. I know that this may look
irritating but I think that this is the right thing to do. I could be
convinced to make this controlled by an option, so that the cursor is
left at the end if the option is unset.

Playing with this I also noticed that there is some weird interaction
going on between inserting such a string and the setting of recexact
(the exact inserted match isn't immediatly accepted, which is wrong if 
auto_menu is unset). I'll have a lokk at this.

Bye
 Sven
