I have tested the patch. It does what it says, but I found an ugly
effect. I don't know GTK+ enough to decide whether this is fixable.

To reproduce:

1. Configure pulseaudio to use Built-In Audio Analog Stereo as the
fallback device.
2. Load module-echo-cancel (just for a sink with a long name).
3. Play something. It should go through "Built-In Audio Analog Stereo"
by default.
4. Start pavucontrol, shrink its window.
5. Using pavucontrol, move that stream to "Built-in Audio Analog
Stereo (echo cancelled with Built-in Audio Analog Stereo)".

Result: the stream title ellipsized to just "...", and the combo box
that allows to select the device becomes wider than the window. I'd
argue that it either should be initially as wide as its widest item
(i.e. the widest sink name in this case), or that the sink names
should also be ellipsized.
