Well, are "I" and "i" the same letters? What about "İ" and "i"? Or "I" and "ı"? What about Greek where uppercasing loses accents (actually not unusual in literate French, either). And what about German ß and SS/SZ? "case-insensitive" is a simple word, but the devil is in the details, and that means basically requiring a system-provided sorting function. And actually the _killer_ detail here is that git _must_ have the same sorting order on every platform, since the order of files in a directory tree affects its SHA-1 sum. So a system-dependent sorting order breaks git interoperability. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
