Hi, as this came up in #-devel, I must admit that I actually prefer the new behaviour slightly: before "ls" used to apply a non-injective mapping to filenames. The new transformation is at least injective, an advantage when dealing with strange filenames in strange encodings.
For sane filenames (only ASCII alphanumerics and a few extra characters, but no whitespace or quotes) nothing changes anyway ;) Note that "ls" and "ls | cat" (output to tty vs no-tty) already differed before. Arguably a different output (C escape) codes might be more readable for users: compare 'new'$'\n''line' vs new\nline where the user has to add the $'...' himself when using the filename in a shell.
