This causes completion failures to be split into two groups: those for
which there was no suggestion and those for which the name was suggested
but the wrong element was selected (as in the case where the correct
element shadows the one that was suggested.
In addition, the both groups of failures are now further grouped by the
location in which they occur.
Finally, failures to complete in hide and show combinators are temporarily
ignored until we can figure out how to complete as if the target identifier
wasn't already in the list.
