Subject: Remove superfluous Clone bound on Entry methods.
X-Git-Tag: 0.12.1~6
X-Git-Url: https://git.chrismorgan.info/anymap/commitdiff_plain/839a6bc6e842b2ae6bbaf4b945ff6f2fbbca1785

Remove superfluous Clone bound on Entry methods.

Thanks to @Kimundi for pointing this out. I presume (without checking)
that they got added along with the CloneAny stuff by accident.

Closes #26.
