Wireshark-dev: [Wireshark-dev] [Patch] Add "Copy as Filter" to the detail-pane context menu

From: Sake Blok <sake@xxxxxxxxxx>

Hi,

Many times I find myself using prepare as filter, just to copy the filter
to another instance of wireshark with a second trace (think of selecting
the tcp.seq to match packets between two traces). As this distroys the filter
that was currently active, I wrote a little patch that adds a "Copy as Filter"
item to the context-menu in the detail-view.

Could someone review this patch and add it to the trunk?

Cheers,


Sake
