:ppop command doesn't work

[Yegappan Lakshmanan]

Hi all,

While developing new tests for the tag functionality, I realized that the
:ppop command which is supposed to pop the preview window tag stack
doesn't work. I am not sure whether this worked in the past. Does anyone
use the :ppop command?

Hi,

Trying to add more tests for the preview tag functionality, I see that
several other features also doesn't work with the preview tag stack.
The preview tag stack feature needs to be revisited.

I'm surprised nobody complained. ":ptag" can be useful. But perhaps
the tag stack in the preview window is less useful.

Anyway, if you can fix it, that would be nice.
