Dash searching: " ' " not considered boundary word

[Leonardo Corato]

Let we have to add a startup application. We should search Startup Applications.
In italian is "Applicazioni d'avvio". (The application real name is gnome-session-properties)
Avvio means startup. I guess Applicazioni is quite clear :)
As it is quite clear I can search using Applicazioni, but of course I would sensibly search avvio (startup) ... but as we search we can see that Applicazioni d'avvio is not found. So Dash search can't see d'avvio as two words.
My guess is that ' is not considered a bounduary word, which is wrong.

That seems to work in the current version (tried with several similar example in french "image" for "d'image", "interface" for "d'interfaces")
