Vmap / vcall gotomap gives confusing error message
When the map name doesn't exist is still prints
This command is not acceptable, see 'vhelp' for more info. on the second line which makes it look like gotomap is not enabled.
Also, when using a prefix that's not unique it says the same thing as when map is not available. (And again, the second line makes it looks like the whole command is invalid).
