It helps: that tells me why the check is only performed on Windows. Since this only affects Windows, please only take this review as data about how someone read the patch. The patch doesn't make non Windows specific code any *less* maintainable, and as a general presumption I assume that the Git for Windows maintainer knows best about what is needed for maintainability of Windows-specific code. But the commit message and docs still don't describe what the desired behavior is. For example, should I be able to check out a revision with a backslash in it (e.g. via Git skipping the offending entry), or is the intended behavior for it to error out and prevent checking out such versions of code? Is there anything we can or should do to prevent people checking in new examples of paths with backslash in them (on all platforms)? Thanks, Jonathan
