Re: [PATCH] log: add %S option (like --source) to log --format




Hi Peff, thanks for the feedback. I tried a variant of the command you
showed and it yielded a seg fault:
```
[ issactrotts ~/git ] ./git diff-tree -s --pretty=tformat:'%S %H %s' HEAD
Segmentation fault: 11
```
I'll see if I can track it down this evening.
