The completion table is not necessarily looked up with the user's typed
string. It's meant to be nothing more than a standardized
representation of a *set* of candidates. How this set is filtered on
the basis of the user's string is under the control of the
completion styles.

The completion-table does not see "the user's input string". It only
sees "a string" (chosen by the completion-style) and should return the
set of candidates which have that string as a prefix. In some cases,
the string it will see is "" and it should hence return the complete
list of candidates (after which the completion style will perform its
own filtering on it).

Great,
