On some platform / shell combos, you may find Git has gone hog-wild with the paging. I.e., you may find it pages things like logs & diffs when there is not even a single page of information in the first place. In this situation, I have found the following Git global config can resolve the issue:
git config --global --replace-all core.pager "less -F -X"https://stackoverflow.com/questions/2183900/how-do-i-prevent-git-diff-from-using-a-pager/2183920
