Description
The NADCON files for Alaska are supposed to cover the longitude range "from 128 to 194 degrees west longitude", and that works. But if the input longitude has been normalized to the range from -180 to +180, then the +nadgrids=alaska doesn't recognize the longitude as inside the grid shift area.
Example input: Attu Island.

By the way, I saw this in version 4.8.0, but it is impossible to specify 4.8.0 in the "Version" field when reporting a ticket.
