Subject: Avoid flickering when moving past the main view's first and last line
X-Git-Tag: tig-0.9~38
X-Git-Url: https://git.distorted.org.uk/~mdw/tig/commitdiff_plain/034001361c7764dacf9cc75dc999eafc25a72637?ds=inline;hp=56b6ea55c47e7dfeb6edd13f8a9702ca78256114

Avoid flickering when moving past the main view's first and last line

In diff mode when first or last item is displayed KEY_UP or KEY_DOWN
respectively cause flickering. I know that I should not press
those keys in that situation, but this annoys me anyway.
