The point is that paths tend to have alphanumeric characters at the start of each component, so it doesn't matter in most cases that it's redefined. People won't notice because c:\path\to\file will continue to work, whether it's by itself or part of a multi-option option. Exceptions are \\host\path and \\.\device, where the error will be so obvious they'll learn quickly. We could find a more complex scheme where \\ is unaffected, but complex is not good and will be wrongly implemented by other programs. Whereas \<char> is very common, well known and easy to get right, even when people guess how it's done, like they do when working out how to quote paths for rsync and ssh. Oh, I'm suddenly thinking that "." should be included in "alphanumeric" :-) -- Jamie -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
