Bearing in mind the example I mentioned in the previous email, maybe we
can add an optional argument to the xref-identifier-at-point-function.

When it's t, the function would return an approximate string (basically
symbol at point, but maybe with minor syntax adjustments), and that
value would be used both in the error message (when we can't find
anything), and as initial input for identifier completion, from
xref-identifier-completion-table.
