A quick run of the testsuite reveals that this assumption is made all over. I am opposed to having this feature be a standard feature of the git-hooks, so you wouldn't have to add an ad hoc check. The way I would do it is by enhancing the git_run function to check for a parameter named "_no_strip" and block the strip() operation when passed as True. You can then implement your check using the usual git interface, with the extra "_no_strip=True" parameter. Do open a GitHub issue if you'd like me to add this check to the git-hooks. I will likely give it less priority because you'll have a way to implement it on your on, but I will get to it eventually. -- Joel
