With read-file-name-completion-ignore-case true, commit
509cbe1c35b3dd005a53ac041f9c87ee53b8e115 breaks existing completion
behavior.  Suppose we have file named fooBarQux.  Previously, if I'd
typed "foobar" and TAB while reading a filename, then the completion
would be "fooBarQux".  Now, it completes as "foobarQux", which is wrong
and breaks, among other things, vc.
