[webkit-gtk] Custom paste handler for editable WebView

[Jim Nelson]

Hello,

The problem Robert wrote about back in July is a big issue for Geary -- 
we've had a number of complaints from our users about this, as it 
affects copy-and-paste in our composer.  Does anyone have any 
suggestions or pointers?  We'd really like to nail this down for our 
upcoming release.

The original Geary bug reporting this is at 
https://bugzilla.gnome.org/show_bug.cgi?id=730495

Thanks,

-- Jim
