[bug-gv] some possibility for bug 24069

[Bernhard R. Link]

I've taken a look at the problem with the overlong scrolled Vlists.
As gv seems to implement its own, changing is relatively easy.

Attached is a try to work around the problem by moving the vertical
scrolling into the vlist. This has the disadvantage that it can only
scroll whole entries and perhaps a couple of more.

Beware that it is quite untested and not very deeply thought about,
but it seems to do something for the TOC.

(File lists and other lists having the same problem would need similar
modifications to make use of this scrolling mechanism. They might
benefit of this to show more of the early entries but it cannot help
with the entries at the end unless the handling of those lists is also
changed to use the new mechanism).

I deem it quite possible that it might have all funny kinds of
side-effects so handle with care, this is mostly some proof-of-concept
so someone else perhaps finds the ideas to implement it properly...

Hochachtungsvoll,
