The \' atom matches with zero-width at the end of string or end of
buffer. As you know $ is a zero-width atom that matches at the end of
line. In theory a filename may contain newlines (in Linux filesystems at
least) and in such situations the $ atom wouldn't necessarily match the
end of the whole filename string.
