For completeness here's a screenshot that shows the situation on a TERM=sun-console text console with the latest code :

After thinking a little more about this issue, I am of the opinion that the best option here is to provide a compile time configure option :

It would be convenient if the -c option could be easily set in the gpg-agent.conf or in some configuration file for pinentry. The workaround that I use now to create a script that I can then use as pinentry-program is extra work because it requires an additional script.

The typo is fixed now and after pulling the latest sources from the repo and configure --disable-ncurses :

My previous patch is not perfect as the screenshot in attach shows. The clear() is not really sufficient as it only redraws the portion below the frame in the new background color (black instead of white).

In the patch in attach I do a clear screen in the non-ncurses case.
