This causes issues with Ruby git hooks, because Ruby version managers
rely on custom settings in PATH to select the Ruby executable,

Even if git wouldn't modify PATH this is still a broken way to do that.
What ruby to execute a hook with is a property of the hook, not of the
user context invoking it.

I probably shouldn't have mentioned Ruby version managers since they are 
not directly related to this issue. I'll try to elaborate on the issue:

* User is relying on a custom path to select their Ruby version. For 
example, let's say the first folder in path is "~/.rubies/2.2.2/bin".
* User runs "/usr/bin/git commit" and a pre-commit hook is triggered.
* The pre-commit hook starts with "#!/us/bin/env ruby" to select the 
Ruby to be used in the hook, but since the path has been changed by 
"/usr/bin/git", the selected ruby will be "/usr/bin/ruby" and not 
"~/.rubies/2.2.2/bin/ruby" as the user would expect.

What's the proper way to do whatever you're saying is done in "a broken 
way"?
