Sorry, but there's only this or that, not both. Either we revert the entire change, including the native shortcut stuff, or we do it completely and fully, including handling virtual drives as symlinks. The alternative is to rewrite the path handling from scratch, which is a massive undertaking I simply don't have the time for. MAX_PATH is not of big concern anymore thiese days. More recent Windows 10 allows long path names in the ANSI interface as well. If you're using dumb tools not being able to cope with such long paths, then use a wrapper converting the affected paths back to a drive letter. It might also be helpful to put matching functionality into the cygpath tool. Patches are welcome.
