* This also handles skipping the first 128 bytes of a .BXY file and the
* front part of a self-extracting GSHK archive.
*
* We try to provide helpful messages about things that aren't archives,
* but try to stay silent about files that are other types of archives.
* That way, if the application is trying a series of libraries to find
* one that will accept the file, we don't generate spurious complaints.
*
* On exit, the stream will be positioned just past the master header.
