I have long and complex passwords that I store in KeePass, and I would like to
be able to paste into Pinentry (when used with thunderbird + enigmail +
gpg4win), however the paste ability is disabled which is very frustrating. I can
perhaps understand copying being disabled, but pasting...

Please can the paste functionality be restored/added to pinentry.
