[PATCH 0/3] stupid git tricks

Here are a few contrib tidbits that I find invaluable when working with
git. They're pretty simple ideas, but I've been using them all for
at least a year[1], and they've made my life more pleasant and
productive. So I thought I'd share.

  [1/3]: contrib: add diff highlight script
  [2/3]: contrib: add git-jump script
  [3/3]: completion: match ctags symbol names in grep patterns

[1] Actually, they all needed significant cleanup for me not to be
    embarrassed to share them, which I just did recently. Undoubtedly I
    introduced scores of new bugs during the cleanup, so take my "at
    least a year" with a grain of salt. The _concepts_ have been proven,
    at least. :)
