[EGIT PATCH 02/10] Recursion and update of all elements regardless of need.

[Robin Rosenberg <robin.rosenberg@dewire.com>]

When selecting an element in the history view viewer.updateElement
is called for every element recursively. If the number of
elements is very largs this results in a stack overflow. This
only happens with Eclipse 3.3 M7 and not M6.

Is it thig bug? https://bugs.eclipse.org/bugs/show_bug.cgi?id=149642
