I didn't read the source but a name like "library" suggests that the
string to match against may contain more than one match. In either
case, using "\\'" means that that string must be constructed carefully
to eliminate a trailing newline.
But wrt my question I was just curious whether the regexp engine
contains an optimization that makes "\\'" match faster than "$".
> string-suffix-p could be even clearer.
