[issue7898] rlcompleter add "real tab" when text is empty feature

[Thomas Fenzl]

Thomas Fenzl added the comment:

It's not (easily) possible to get the invoked character that caused the completion function. 
Multiple keys can be bound to complete and the bindable function rl_complete provided in libreadline does not forward the invoking key to rl_complete_internal, through which Completer.complete is eventually called.
