Thanks for finding this strange bug! I don't even have LEFT SINGLE
QUOTATION MARK on my keyboard and wasn't aware of its existance, so this
must be a bug caused by 'copy&paste' or so. No idea where this comes
from.
Actually, for me it wasn't even a bug since it only appereared in the
comment-sections (and thus in the README files) of the libraries, not in
the code (in my dot emacs) itself.
I fixed that and pushed new versions on Github. Sorry for the hassle.
