I take issue with the title. Is there a VCS that commits every keystroke individually? No, because that wouldn't be useful. There is always a choice in when and what to commit. The only thing with git is that it makes it easy to change things after the fact, but you can achieve something pretty close in svn by simply not committing until you're done with a feature.

It's not about faking anything, it's a question of what information you want to leave for posterity. And frankly I come down pretty strongly against preserving warts for warts sake. As a rule of thumb, commits should be as fine-grained as possible without breaking the build. In my experience more detail than that gives diminishing returns in utility as the signal-to-noise ratio drops and you get overwhelmed with details which only represent a brain fart on the part of the developer, and never had any measurable impact on the project.
