Feature request: Number of matches in Gtk::EntryCompletion

[Matthias Kaeppler <nospam digitalraid com>]

You should really be able to figure out how many matches were found. 
This whole EntryCompletion class is a very nice thing, but its public 
API is very minimalistic, you have absolutely no means to get 
information about the possible completions.

Something like get_n_matches() should really be part of its interface. 
It would return the size of the internal container holding the possible 
completions.

It's useful, and trivial to implement.

What do you think?
