Scrolling notification works by callingscrolltext{}
with with 2 values between 0 and 1
for the beginning and the end of the view relative to the total length.
When a long diff with several files is loaded,
the diff view length is updated several times
and causes executions of scrolltext{} even when
the current view never changed.
Every time scrolltext{} is executed,
a entry in the file list is selected and scrolled to.
This makes it impossible for a user to scroll the file list
while a long diff is still loading.

Hi,
i used v3 of the Synchronize patch (+ the 2 fixes on top)
for some time now on mingw,
but i found a slight problem for my usage.
While the diff is loaded, the file list on the right side always scrolls up.
When a single revision touches hundreds of files [1] the loading takes
quite long.
During the diff loading i want to scroll down in the file list to the
relevant file i
am interested in. But the file list jumps up all the time.
Please review/test the patch carefully before applying,
since i do not often work with tcl/tk :-)
(Or suggest better ways to solve this problem)
Greetings Peter
[1] I imported history of a historic project. Each release is represented
by a single commit. Thus one commit contains a lot of files/big amount
of changes.
But most times i am interested in only a single file in the middle of
the file list.
