When pacman is installed, an empty trustdb is created if it is non-existent. The --import-trustdb option allows users to import their own trustdb into pacman's gpgdir to facilitate signature verification.

None of this works for translated messages. Please follow the
The name "import" leads me to believe it doesn't overwrite, but I think this in fact does that. Is there any way we can actually do a merge of the existing with the trust db one is pulling from? pattern established in makepkg in the CLEANCACHE code (line ~1810). This way the same strings can be used for gettext, and "N" is the obvious default, which I think it should be. You also didn't translate 'n' or 'no'; we should just use the Y/YES from makepkg over again. Don't even worry about the valid choice stuff; if you don't type y or yes, you lose. I'd also ditch the unnecessary "is preserved" message unless other people think it is required.
