This provides a control in the preferences pane for the limit on how many tags or heads are displayed with the commit details under the Branch(es), Precedes and Follows headings. This limit is now saved in ~/.gitk so that changes are persistent. This also applies word-wrapping to the list of tags or heads under the Branch, Precedes and Follows headings, so that long lists are more readable. Signed-off-by: Paul Mackerras <paulus@samba.org>
