PATCH: _history_complete_word

[Sven Wischnowsky <wischnow@informatik.hu-berlin.de>]

I think _history_complete_word could use the new tag label stuff, too.


There is something in this function I don't understand:

There is always one match inserted immediately. That's ok for a
function like this, but why does _h_c_w then test for
`$compstate[insert] = menu'? It means that this is almost unusable
without normally using menucompletion (one can't cycle through the
matches).

Or did setting compstate[insert] to a number once start menucompletion 
so that it reported `menu' in $compstate[insert] on the next
invocation? But we can test it with $compstate[old_insert] now.

No patch for this, because I'm not completely sure which behaviour is
desired.


Bye
 Sven
